Error description
Error Message: N/A . Stack Trace: N/A . Stale version of class file is loaded.
Local fix
The problem can be avoided by disabling the use of shareclasses (remove -Xshareclasses option). Note that this can have a negative performance impact.
Problem summary
If a shared class associated with a jar file is loaded, and then the jar file is modified on disk, if a new classloader is created on the modified jar file in the same running process, the class from the original jar will be loaded from the shared cache.
Problem conclusion
This APAR will be fixed in the following Java Releases: 7 SR7 (7.0.7.0) 6 R1 SR8 (6.1.8.0) . The JVM has been updated to ensure that the modified jar file is used to load the class.
Temporary fix
