Download Description

PM88913 resolves the following problem:

ERROR DESCRIPTION:
The GenPluginCfg utility may throw a java.lang.IncompatibleClassChangeError when reading applications.

LOCAL FIX:
none

PROBLEM SUMMARY

USERS AFFECTED:
All users of IBM WebSphere Application Server V8.5

PROBLEM DESCRIPTION:
The GenPluginCfg utility may throw a java.lang.IncompatibleClassChangeError when reading applications.

RECOMMENDATION:
None

WebSphere Application Server v8.5 includes version 3.2 and version 4.0 of the ASM bytecode scanning library. The GenPluginCfg utility does not use OSGi internally and is unable to enforce bundle versioning. Because of incompatibilities between the two libraries, GenPluginCfg may throw an IncompatibleClassChangeError when processing Java Enterprise Edition 5 or 6 applications:
java.lang.IncompatibleClassChangeError:
org.objectweb.asm.ClassVisitor
at java.lang.ClassLoader.defineClassImpl(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:262)

PROBLEM CONCLUSION:
The scripts for GenPluginCfg utility were updated to ensure the correct ASM binary is first on the classpath.

The following files were updated:

For Microsoft Windows operating systems:
* INSTALL_ROOT/bin/GenPluginCfg.bat
For all other operating systems:
* INSTALL_ROOT/bin/GenPluginCfg.sh

The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.1. Please refer to the Recommended Updates page for delivery information:
