Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Session Initiation Protocol (SIP)    *
  ****************************************************************
  * PROBLEM DESCRIPTION: SIP Container occasionally throws       *
  *                      NullPointerException                    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The SIP Container might throw a NullPointerException when it
  processes a response from a proxy branch and a session on
  which the response received is during invalidation.
  

Problem conclusion

• The fix allows not to process a response from a proxy
  branch if its session / transaction user is invalidating.
  
  A new custom property "process.invalid.transaction.response"
  is added which defaults to true. To enable the new behavior
  need to set the property to be 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 Recommended
