Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server web applications * **************************************************************** * PROBLEM DESCRIPTION: Web applications with resource * * injection intermittently fail to * * start with * * ConcurrentModificationException * **************************************************************** * RECOMMENDATION: * **************************************************************** Web applications with resource injection (@Resource) may fail to start with a ConcurrentModificationException from ReferenceContextImpl. This is a very intermittent problem that occurs when the server is processing resource injection for dynamic web modules.
Problem conclusion
WebSphere resource injection processing has been updated to properly handle the concurrency of dynamic web modules. The ConcurrentModificationException will no longer occur and the web application will start successfully. The fix for this APAR is currently targeted for inclusion in fix pack 9.0.0.11.
