Description
FlexibleStringExpander.java:245, NP_EQUALS_SHOULD_HANDLE_NULL_ARGUMENT
- NP: org.apache.ofbiz.base.util.string.FlexibleStringExpander$Key.equals(Object) does not check for null argument
This implementation of equals(Object) violates the contract defined by java.lang.Object.equals() because it does not check for null being passed as the argument. All equals() methods should return false if passed a null value.
FlexibleStringExpander.java:444, REC_CATCH_EXCEPTION
- REC: Exception is caught when Exception is not thrown in org.apache.ofbiz.base.util.string.FlexibleStringExpander.expandString(Map, TimeZone, Locale)
This method uses a try-catch block that catches Exception objects, but Exception is not thrown within the try block, and RuntimeException is not explicitly caught. It is a common bug pattern to say try
{ ... } catch (Exception e) { something } as a shorthand for catching a number of types of exception each of whose catch blocks is identical, but this construct also accidentally catches RuntimeException as well, masking potential bugs.A better approach is to either explicitly catch the specific exceptions that are thrown, or to explicitly catch RuntimeException exception, rethrow it, and then catch all non-Runtime Exceptions, as shown below:
try { ... } catch (RuntimeException e) { throw e; } catch (Exception e) { ... deal with all non-runtime exceptions ... }
FlexibleStringExpander.java:540, SE_NO_SERIALVERSIONID
- SnVI: org.apache.ofbiz.base.util.string.FlexibleStringExpander$ConstSimpleElem 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.

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

- OS: org.apache.ofbiz.base.util.string.UelFunctions.writeXmlDocument(String, Node, String, boolean, boolean, int) may fail to close stream on exception
The method creates an IO stream object, does not assign it to any fields, pass it to other methods, or return it, and does not appear to close it on all possible exception paths out of the method. This may result in a file descriptor leak. It is generally a good idea to use a finally block to ensure that streams are closed.

- CI: Class org.apache.ofbiz.base.util.string.UelUtil is final but declares protected field org.apache.ofbiz.base.util.string.UelUtil.module
This class is declared to be final, but declares fields to be protected. Since the class is final, it can not be derived from, and the use of protected is confusing. The access modifier for the field should be changed to private or public to represent the true use for the field.

- Se: Class org.apache.ofbiz.base.util.string.UelUtil$BasicValueExpression defines non-transient non-serializable instance field elContext
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.
