Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Attempt to log translated message * * results in a class loader deadlock * **************************************************************** * RECOMMENDATION: * **************************************************************** When the WebSphere Application Server class loader encounters an exception reading a jar file during class loading, it attempts to log a translated error message (WSVR0120E). That triggers an attempt to load a message bundle, which utilizes the thread context class loader, a pattern that is susceptible to deadlocks in some packaging configurations (for example, if there are class loads originating in the EAR-level class loader while the WAR-level loader is set as the context class loader).
Problem conclusion
The translated message was relocated from the error stream to the debug stream and is no longer translated, avoiding the deadlock condition. The fix for this APAR is currently targeted for inclusion in fix packs 8.0.0.10 and 8.5.5.4.
