    ****************************************************************
    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.  Please refer to the
