IBM® WebSphere® Application Server Classloader Cumulative
Fix for V 5.0 and 5.0.1
Download Description
This is a cumulative Runtime and Classloader fix set, correcting the
following problems:
Addressed customer problems:
- PQ72658
Class-Path entries in jar files configured as shared libraries are not
being added to the class loader, resulting in "class not found" errors.
For example, if a.jar is configured as part of a shared library, and the
manifest of a.jar lists a Class-Path dependency on b.jar, then classes in
b.jar may not be found at runtime.
- PQ73332
ConcurrentModificationException in ReloadableClassLoader. In environments
where dynamic class reloading is enabled (such as the WebSphere
Application Server Unit Test Environment), intermittent exceptions of type
java.util.ConcurrentModificationException may be experienced.
- PQ75469
If a shared library is defined as a directory only, the jar files in the
directory may not added to the classloader, resulting in "class not found"
errors. For V5.0, this occurs with server associated shared libraries. For
V5.0.2, this also occurs with application associated shared libraries.
- Additional fixes
ReloadTaskTimer not cancelled. As applications are stopped and restarted,
the corresponding timer task that detects class file changes is not
cancelled.
All of these fixes, with the exception of PQ75469, are in Fix Pack 5.0.2.
The PQ75469 fix will be available in the next Service Pack.
