Error description
A deadlock can occur when stopping a compoistion unit that contains Blueprint shortly after the composition unit is started.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Composition Unit cannot be stopped * * due to deadlock. * **************************************************************** * RECOMMENDATION: * **************************************************************** The same lock object was used for different purposes and resulted in a deadlock.
Problem conclusion
This APAR avoids the deadlock by introducing a new lock to create a more granular locking module. The fix for this APAR is currently targeted for inclusion in fix pack 8.0.0.8 and 8.5.5.1.
