Short description: JVM core dumps in ClassLoader.defineClass0().

Full problem description:

We are running JBOSS 3.2.1. When we have duplicate class, we get the following error message
              java.lang.LinkageError: duplicate class definition:
    com/nortel/mftP/dmlP/modelP/faultP/workflowP/AlarmClearWorkflowC

and shortly after the JVM core dumps. However, we dont see this
behavor with J2SE 1.4.0 or 1.4.1_05. This is 1.4.2 specific.
