Minor Description
- JavaMailContainer.java:127, RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE
RCN: Redundant nullcheck of store, which is known to be non-null in org.apache.ofbiz.service.mail.JavaMailContainer.start()
This method contains a redundant check of a known non-null value against the constant null.
- JavaMailContainer.java:167, DM_CONVERT_CASE
Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.service.mail.JavaMailContainer.makeSession(ContainerConfig$Configuration$Property)
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.
- JavaMailContainer.java:245, DM_BOXED_PRIMITIVE_FOR_PARSING
Bx: Boxing/unboxing to parse a primitive org.apache.ofbiz.service.mail.JavaMailContainer.updateUrlName(URLName, Properties)
A boxed primitive is created from a String, just to extract the unboxed primitive value. It is more efficient to just call the static parseXXX method.
- JavaMailContainer.java:269, SIC_INNER_SHOULD_BE_STATIC
SIC: Should org.apache.ofbiz.service.mail.JavaMailContainer$LoggingStoreListener be a static inner class?
This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary. If possible, the class should be made static.
- JavaMailContainer.java:274, SF_SWITCH_NO_DEFAULT
SF: Switch statement found in org.apache.ofbiz.service.mail.JavaMailContainer$LoggingStoreListener.notification(StoreEvent) 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.
- MimeMessageWrapper.java:50, SE_NO_SERIALVERSIONID
SnVI: org.apache.ofbiz.service.mail.MimeMessageWrapper 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.
- MimeMessageWrapper.java:68, IS2_INCONSISTENT_SYNC
IS: Inconsistent synchronization of org.apache.ofbiz.service.mail.MimeMessageWrapper.session; locked 75% 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.
- MimeMessageWrapper.java:69, IS2_INCONSISTENT_SYNC
IS: Inconsistent synchronization of org.apache.ofbiz.service.mail.MimeMessageWrapper.mailProperties; locked 50% of time

- MimeMessageWrapper.java:142, PZLA_PREFER_ZERO_LENGTH_ARRAYS
PZLA: Should org.apache.ofbiz.service.mail.MimeMessageWrapper.getHeader(String) return a zero length array rather than null?
It is often a better design to return a length zero array rather than a null reference to indicate that there are no results (i.e., an empty list of results). This way, no explicit check for null is needed by clients of the method.
On the other hand, using null to indicate "there is no answer to this question" is probably appropriate. For example, File.listFiles() returns an empty list if given a directory containing no files, and returns null if the file is not a directory.

- MimeMessageWrapper.java:294, DM_CONVERT_CASE
Dm: Use of non-localized String.toUpperCase() or String.toLowerCase() in org.apache.ofbiz.service.mail.MimeMessageWrapper.getMessageBody()
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.

versions instead.
- MimeMessageWrapper.java:526, DM_DEFAULT_ENCODING
Dm: Found reliance on default encoding in org.apache.ofbiz.service.mail.MimeMessageWrapper.getTextFromStream(InputStream): new String(byte[], int, int)
Found a call to a method which will perform a byte to String (or String to byte) conversion, and will assume that the default platform encoding is suitable. This will cause the application behaviour to vary between platforms. Use an alternative API and specify a charset name or Charset object explicitly.
