Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0 and v8.5 Session Initiation * * Protocol (SIP) * **************************************************************** * PROBLEM DESCRIPTION: SIP Container occasionally throws * * NullPointerException on stray * * responses. * **************************************************************** * RECOMMENDATION: * **************************************************************** The SIP Container might throw a NullPointerException when processing a stray response on a request which session is undergoing invalidation.
Problem conclusion
The SIP container verifies a session state on a stray response and processes the response if its session is still valid. In addition, it fixes a memory leak caused by PM84627. The fix is working when the custom property "process.invalid.transaction.response" added in PM84627 set to false. The fix for this APAR is currently targeted for inclusion in fix packs 8.0.0.7 and 8.5.5.1.
