Description

• DispatchContext.java:-1, SE_TRANSIENT_FIELD_NOT_RESTORED
  Se: The field org.apache.ofbiz.service.DispatchContext.loader is transient but isn't set by deserialization

This class contains a field that is updated at multiple places in the class, thus it seems to be part of the state of the class. However, since the field is marked as transient and not set in readObject or readResolve, it will contain the default value in any deserialized instance of the class.

• DispatchContext.java:-1, SE_TRANSIENT_FIELD_NOT_RESTORED
  Se: The field org.apache.ofbiz.service.DispatchContext.dispatcher is transient but isn't set by deserialization

This class contains a field that is updated at multiple places in the class, thus it seems to be part of the state of the class. However, since the field is marked as transient and not set in readObject or readResolve, it will contain the default value in any deserialized instance of the class.

• DispatchContext.java:56, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.DispatchContext is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• DispatchContext.java:209, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of serviceMap, which is known to be non-null in org.apache.ofbiz.service.DispatchContext.getModelService(String)

This method contains a redundant check of a known non-null value against the constant null.

• DispatchContext.java:273, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of serviceMap, which is known to be non-null in org.apache.ofbiz.service.DispatchContext.getGlobalServiceMap()

This method contains a redundant check of a known non-null value against the constant null.

• GeneralServiceException.java:63, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of org.apache.ofbiz.base.util.GeneralException.getNested(), which is known to be non-null in org.apache.ofbiz.service.GeneralServiceException.returnError(String)

This method contains a redundant check of a known non-null value against the constant null.

• GenericAbstractDispatcher.java:86, REC_CATCH_EXCEPTION
  REC: Exception is caught when Exception is not thrown in org.apache.ofbiz.service.GenericAbstractDispatcher.schedule(String, String, String, Map, long, int, int, int, long, int)

This method uses a try-catch block that catches Exception objects, but Exception is not thrown within the try block, and RuntimeException is not explicitly caught. It is a common bug pattern to say try

{ ... }

catch (Exception e)

{ something }

as a shorthand for catching a number of types of exception each of whose catch blocks is identical, but this construct also accidentally catches RuntimeException as well, masking potential bugs.

A better approach is to either explicitly catch the specific exceptions that are thrown, or to explicitly catch RuntimeException exception, rethrow it, and then catch all non-Runtime Exceptions, as shown below:

try

{ ... }

catch (RuntimeException e)

{ throw e; }

catch (Exception e)

{ ... deal with all non-runtime exceptions ... }

• GenericDispatcherFactory.java:32, MS_PKGPROTECT
  MS: org.apache.ofbiz.service.GenericDispatcherFactory.ecasDisabled should be package protected

A mutable static field could be changed by malicious code or by accident. The field could be made package protected to avoid this vulnerability.

• GenericDispatcherFactory.java:49, SIC_INNER_SHOULD_BE_STATIC
  SIC: Should org.apache.ofbiz.service.GenericDispatcherFactory$GenericDispatcher be a static inner class?

This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary. If possible, the class should be made static.

• GenericDispatcherFactory.java:72, ST_WRITE_TO_STATIC_FROM_INSTANCE_METHOD
  ST: Write to static field org.apache.ofbiz.service.GenericDispatcherFactory.ecasDisabled from instance method org.apache.ofbiz.service.GenericDispatcherFactory$GenericDispatcher.disableEcas()

This instance method writes to a static field. This is tricky to get correct if multiple instances are being manipulated, and generally bad practice.

• GenericDispatcherFactory.java:77, ST_WRITE_TO_STATIC_FROM_INSTANCE_METHOD
  ST: Write to static field org.apache.ofbiz.service.GenericDispatcherFactory.ecasDisabled from instance method org.apache.ofbiz.service.GenericDispatcherFactory$GenericDispatcher.enableEcas()

This instance method writes to a static field. This is tricky to get correct if multiple instances are being manipulated, and generally bad practice.

• GenericResultWaiter.java:29, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.GenericResultWaiter is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• GenericResultWaiter.java:52, NO_NOTIFY_NOT_NOTIFYALL
  No: Using notify rather than notifyAll in org.apache.ofbiz.service.GenericResultWaiter.receiveResult(Map)

This method calls notify() rather than notifyAll(). Java monitors are often used for multiple conditions. Calling notify() only wakes up one thread, meaning that the thread woken up might not be the one waiting for the condition that the caller just satisfied.

• GenericResultWaiter.java:64, NO_NOTIFY_NOT_NOTIFYALL
  No: Using notify rather than notifyAll in org.apache.ofbiz.service.GenericResultWaiter.receiveThrowable(Throwable)

This method calls notify() rather than notifyAll(). Java monitors are often used for multiple conditions. Calling notify() only wakes up one thread, meaning that the thread woken up might not be the one waiting for the condition that the caller just satisfied.

• ModelParam.java:41, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.ModelParam is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• ModelParam.java:209, HE_EQUALS_USE_HASHCODE
  HE: org.apache.ofbiz.service.ModelParam defines equals and uses Object.hashCode()

This class overrides equals(Object), but does not override hashCode(), and inherits the implementation of hashCode() from java.lang.Object (which returns the identity hash code, an arbitrary value assigned to the object by the VM). Therefore, the class is very likely to violate the invariant that equal objects must have equal hashcodes.

If you don't think instances of this class will ever be inserted into a HashMap/HashTable, the recommended hashCode implementation to use is:

public int hashCode()

{ assert false : "hashCode not designed"; return 42; // any arbitrary constant will do }

• ModelParam.java:209, EQ_SELF_USE_OBJECT
  Eq: org.apache.ofbiz.service.ModelParam defines equals(ModelParam) method and uses Object.equals(Object)

This class defines a covariant version of the equals() method, but inherits the normal equals(Object) method defined in the base java.lang.Object class. The class should probably define a boolean equals(Object) method.

• ModelParam.java:297, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.ModelParam$ModelParamValidator is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• ModelPermGroup.java:32, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.ModelPermGroup is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• ModelPermission.java:35, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.ModelPermission is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• ModelPermission.java:108, NP_LOAD_OF_KNOWN_NULL_VALUE
  NP: Load of known null value in org.apache.ofbiz.service.ModelPermission.evalRoleMember(GenericValue)

The variable referenced at this point is known to be null due to an earlier check against null. Although this is valid, it might be a mistake (perhaps you intended to refer to a different variable, or perhaps the earlier check to see if the variable is null should have been a check to see if it was non-null).

• ModelPermission.java:129, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of permission, which is known to be non-null in org.apache.ofbiz.service.ModelPermission.evalPermissionService(ModelService, DispatchContext, Map)

This method contains a redundant check of a known non-null value against the constant null.

• ModelPermission.java:150, NP_LOAD_OF_KNOWN_NULL_VALUE
  NP: Load of known null value in org.apache.ofbiz.service.ModelPermission.evalPermissionService(ModelService, DispatchContext, Map)

The variable referenced at this point is known to be null due to an earlier check against null. Although this is valid, it might be a mistake (perhaps you intended to refer to a different variable, or perhaps the earlier check to see if the variable is null should have been a check to see if it was non-null).

• ModelService.java:-1, SE_BAD_FIELD
  Se: Class org.apache.ofbiz.service.ModelService defines non-transient non-serializable instance field implServices

This Serializable class defines a non-primitive instance field which is neither transient, Serializable, or java.lang.Object, and does not appear to implement the Externalizable interface or the readObject() and writeObject() methods. Objects of this class will not be deserialized correctly if a non-Serializable object is stored in this field.

• ModelService.java:-1, SE_BAD_FIELD
  Se: Class org.apache.ofbiz.service.ModelService defines non-transient non-serializable instance field internalGroup

This Serializable class defines a non-primitive instance field which is neither transient, Serializable, or java.lang.Object, and does not appear to implement the Externalizable interface or the readObject() and writeObject() methods. Objects of this class will not be deserialized correctly if a non-Serializable object is stored in this field.

• ModelService.java:-1, SE_BAD_FIELD
  Se: Class org.apache.ofbiz.service.ModelService defines non-transient non-serializable instance field metrics

This Serializable class defines a non-primitive instance field which is neither transient, Serializable, or java.lang.Object, and does not appear to implement the Externalizable interface or the readObject() and writeObject() methods. Objects of this class will not be deserialized correctly if a non-Serializable object is stored in this field.

• ModelService.java:-1, SE_BAD_FIELD
  Se: Class org.apache.ofbiz.service.ModelService defines non-transient non-serializable instance field notifications

This Serializable class defines a non-primitive instance field which is neither transient, Serializable, or java.lang.Object, and does not appear to implement the Externalizable interface or the readObject() and writeObject() methods. Objects of this class will not be deserialized correctly if a non-Serializable object is stored in this field.

• ModelService.java:84, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.ModelService is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field.

To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• ModelService.java:329, IT_NO_SUCH_ELEMENT
  It: org.apache.ofbiz.service.ModelService$1$1.next() can't throw NoSuchElementException

This class implements the java.util.Iterator interface. However, its next() method is not capable of throwing java.util.NoSuchElementException. The next() method should be changed so it throws NoSuchElementException if is called when there are no more elements to return.

• ModelService.java:383, IS2_INCONSISTENT_SYNC
  IS: Inconsistent synchronization of org.apache.ofbiz.service.ModelService.inheritedParameters; locked 50% of time

The fields of this class appear to be accessed inconsistently with respect to synchronization. This bug report indicates that the bug pattern detector judged that

The class contains a mix of locked and unlocked accesses,
The class is not annotated as javax.annotation.concurrent.NotThreadSafe,
At least one locked access was performed by one of the class's own methods, and
The number of unsynchronized field accesses (reads and writes) was no more than one third of all accesses, with writes being weighed twice as high as reads
A typical bug matching this bug pattern is forgetting to synchronize one of the methods in a class that is intended to be thread-safe.

You can select the nodes labeled "Unsynchronized access" to show the code locations where the detector believed that a field was accessed without synchronization.

Note that there are various sources of inaccuracy in this detector; for example, the detector cannot statically detect all situations in which a lock is held. Also, even when the detector is accurate in distinguishing locked vs. unlocked accesses, the code in question may still be correct.

• ModelService.java:480, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of params, which is known to be non-null in org.apache.ofbiz.service.ModelService.updateDefaultValues(Map, String)

This method contains a redundant check of a known non-null value against the constant null.

• ModelServiceReader.java:-1, SE_BAD_FIELD
  Se: Class org.apache.ofbiz.service.ModelServiceReader defines non-transient non-serializable instance field delegator

This Serializable class defines a non-primitive instance field which is neither transient, Serializable, or java.lang.Object, and does not appear to implement the Externalizable interface or the readObject() and writeObject() methods. Objects of this class will not be deserialized correctly if a non-Serializable object is stored in this field.

• ModelServiceReader.java:60, SE_NO_SERIALVERSIONID
  SnVI: org.apache.ofbiz.service.ModelServiceReader is Serializable; consider declaring a serialVersionUID

This class implements the Serializable interface, but does not define a serialVersionUID field. A change as simple as adding a reference to a .class object will add synthetic fields to the class, which will unfortunately change the implicit serialVersionUID (e.g., adding a reference to String.class will generate a static field class$java$lang$String). Also, different source code to bytecode compilers may use different naming conventions for synthetic variables generated for references to class objects or inner classes. To ensure interoperability of Serializable across versions, consider adding an explicit serialVersionUID.

• ModelServiceReader.java:111, UCF_USELESS_CONTROL_FLOW
  UCF: Useless control flow in org.apache.ofbiz.service.ModelServiceReader.getModelServices()

This method contains a useless control flow statement, where control flow continues onto the same place regardless of whether or not the branch is taken. For example, this is caused by having an empty statement block for an if statement:

if (argv.length == 0)

{ // TODO: handle this case }

• ModelServiceReader.java:154, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of service, which is known to be non-null in org.apache.ofbiz.service.ModelServiceReader.getModelServices()

This method contains a redundant check of a known non-null value against the constant null.

• RunningService.java:59, EI_EXPOSE_REP
  EI: org.apache.ofbiz.service.RunningService.getStartStamp() may expose internal representation by returning RunningService.startStamp

Returning a reference to a mutable object value stored in one of the object's fields exposes the internal representation of the object. If instances are accessed by untrusted code, and unchecked changes to the mutable object would compromise security or other important properties, you will need to do something different. Returning a new copy of the object is better approach in many situations.

• RunningService.java:63, EI_EXPOSE_REP
  EI: org.apache.ofbiz.service.RunningService.getEndStamp() may expose internal representation by returning RunningService.endStamp

Returning a reference to a mutable object value stored in one of the object's fields exposes the internal representation of the object. If instances are accessed by untrusted code, and unchecked changes to the mutable object would compromise security or other important properties, you will need to do something different. Returning a new copy of the object is better approach in many situations.

• RunningService.java:72, HE_EQUALS_USE_HASHCODE
  HE: org.apache.ofbiz.service.RunningService defines equals and uses Object.hashCode()

This class overrides equals(Object), but does not override hashCode(), and inherits the implementation of hashCode() from java.lang.Object (which returns the identity hash code, an arbitrary value assigned to the object by the VM). Therefore, the class is very likely to violate the invariant that equal objects must have equal hashcodes.

If you don't think instances of this class will ever be inserted into a HashMap/HashTable, the recommended hashCode implementation to use is:

public int hashCode()

{ assert false : "hashCode not designed"; return 42; // any arbitrary constant will do }

• ServiceContainer.java:57, ST_WRITE_TO_STATIC_FROM_INSTANCE_METHOD
  ST: Write to static field org.apache.ofbiz.service.ServiceContainer.dispatcherFactory from instance method org.apache.ofbiz.service.ServiceContainer.init(List, String, String)

This instance method writes to a static field. This is tricky to get correct if multiple instances are being manipulated, and generally bad practice.

• ServiceDispatcher.java:73, MS_SHOULD_BE_FINAL
  MS: org.apache.ofbiz.service.ServiceDispatcher.dispatchers isn't final but should be

This static field public but not final, and could be changed by malicious code or by accident from another package. The field could be made final to avoid this vulnerability.

• ServiceDispatcher.java:76, MS_PKGPROTECT
  MS: org.apache.ofbiz.service.ServiceDispatcher.enableJM should be package protected

A mutable static field could be changed by malicious code or by accident. The field could be made package protected to avoid this vulnerability.

• ServiceDispatcher.java:77, MS_PKGPROTECT
  MS: org.apache.ofbiz.service.ServiceDispatcher.enableJMS should be package protected

A mutable static field could be changed by malicious code or by accident. The field could be made package protected to avoid this vulnerability.

• ServiceDispatcher.java:78, MS_PKGPROTECT
  MS: org.apache.ofbiz.service.ServiceDispatcher.enableSvcs should be package protected

A mutable static field could be changed by malicious code or by accident. The field could be made package protected to avoid this vulnerability.

• ServiceDispatcher.java:118, NP_NULL_ON_SOME_PATH
  NP: Possible null pointer dereference of delegator in new org.apache.ofbiz.service.ServiceDispatcher(Delegator, boolean, boolean)

There is a branch of statement that, if executed, guarantees that a null value will be dereferenced, which would generate a NullPointerException when the code is executed. Of course, the problem might be that the branch or statement is infeasible and that the null pointer exception can't ever be executed; deciding that is beyond the ability of FindBugs.

• ServiceDispatcher.java:425, DM_CONVERT_CASE
  Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.service.ServiceDispatcher.runSync(String, ModelService, Map, boolean)

A String is being converted to upper or lowercase, using the platform's default encoding. This may result in improper conversions when used with international characters. Use the

String.toUpperCase( Locale l )
String.toLowerCase( Locale l )
versions instead.

• ServiceDispatcher.java:463, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of errMsg, which is known to be non-null in org.apache.ofbiz.service.ServiceDispatcher.runSync(String, ModelService, Map, boolean)

This method contains a redundant check of a known non-null value against the constant null.

• ServiceDispatcher.java:464, UCF_USELESS_CONTROL_FLOW
  UCF: Useless control flow in org.apache.ofbiz.service.ServiceDispatcher.runSync(String, ModelService, Map, boolean)

This method contains a useless control flow statement, where control flow continues onto the same place regardless of whether or not the branch is taken. For example, this is caused by having an empty statement block for an if statement:

if (argv.length == 0)

{ // TODO: handle this case }

• ServiceDispatcher.java:1025, HE_USE_OF_UNHASHABLE_CLASS
  HE: org.apache.ofbiz.service.RunningService doesn't define a hashCode() method but is used in a hashed data structure in org.apache.ofbiz.service.ServiceDispatcher.logService(String, ModelService, int)

A class defines an equals(Object) method but not a hashCode() method, and thus doesn't fulfill the requirement that equal objects have equal hashCodes. An instance of this class is used in a hash data structure, making the need to fix this problem of highest importance.

• ServiceSynchronization.java:55, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
  RCN: Redundant nullcheck of sync, which is known to be non-null in org.apache.ofbiz.service.ServiceSynchronization.registerCommitService(DispatchContext, String, String, Map, boolean, boolean)

  RCN: Redundant nullcheck of sync, which is known to be non-null in org.apache.ofbiz.service.ServiceSynchronization.registerRollbackService(DispatchContext, String, String, Map, boolean, boolean)

This method contains a redundant check of a known non-null value against the constant null.

• ServiceUtil.java:557, NP_NULL_ON_SOME_PATH
  NP: Possible null pointer dereference of job in org.apache.ofbiz.service.ServiceUtil.cancelJob(DispatchContext, Map)

There is a branch of statement that, if executed, guarantees that a null value will be dereferenced, which would generate a NullPointerException when the code is executed. Of course, the problem might be that the branch or statement is infeasible and that the null pointer exception can't ever be executed; deciding that is beyond the ability of FindBugs.

• ServiceUtil.java:595, NP_NULL_ON_SOME_PATH
  NP: Possible null pointer dereference of job in org.apache.ofbiz.service.ServiceUtil.cancelJobRetries(DispatchContext, Map)

There is a branch of statement that, if executed, guarantees that a null value will be dereferenced, which would generate a NullPointerException when the code is executed. Of course, the problem might be that the branch or statement is infeasible and that the null pointer exception can't ever be executed; deciding that is beyond the ability of FindBugs.

• ServiceUtil.java:648, NP_NULL_PARAM_DEREF
  NP: Null passed for nonnull parameter of org.apache.ofbiz.base.util.UtilMisc.toMap(Object[]) in org.apache.ofbiz.service.ServiceUtil.makeContext(Object[])

This method call passes a null value for a non-null method parameter. Either the parameter is annotated as a parameter that should always be non-null, or analysis has shown that it will always be dereferenced.

• ServiceXaWrapper.java:258, SF_SWITCH_NO_DEFAULT
  SF: Switch statement found in org.apache.ofbiz.service.ServiceXaWrapper.runService(String, Map, boolean, int, int) where default case is missing

This method contains a switch statement where default case is missing. Usually you need to provide a default case.

Because the analysis only looks at the generated bytecode, this warning can be incorrect triggered if the default case is at the end of the switch statement and the switch statement doesn't contain break statements for other cases.
