Problem summary
**************************************************************** USERS AFFECTED: Users of WebSphere Enterprise Service Bus, WebSphere Process Server or Business Process Manager who see a FlowBuildException from a flow or a subflow with a resulting FFDC showing a ConcurrentModificationException. **************************************************************** PROBLEM SUMMARY: The node properties from a flow or subflow were previously stored in a Hash Map. Under certain conditions accessing this Hash Map could result in a ConcurrentModificationException and the resulting FlowBuildException which prevents the flow being used. This would be an intermittent problem not effecting every message into the flow. The Hash Map was replaced with a ConcurrentHashMap to avoid this issue
Problem conclusion
The code was altered to use a ConcurrentHashMap to avoid the issue. This code fix was targeted to be included in the following fix packs: 6.2.0 Fix Pack 4 (v6.2.0.4) 7.0.0 Fix Pack 6 (v7.0.0.6) 7.5.1 Fix Pack 2 (v7.5.1.2)
Temporary fix
