Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V8.0 and V8.5 on z/OS                *
****************************************************************
* PROBLEM DESCRIPTION: When an HTTP response fails, a double   *
*                      delete of the ORBR object will happen   *
*                      by both the Java and native code.       *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
On WebSphere Application Server for z/OS, when an HTTP
response fails, the return code sent back to the native code
triggers a delete of the ORBR object. However, on the Java
end, the ORBR pointer is not reset to 0. This causes Java
code to also attempt a delete of the ORBR object which will
often (but not always) produce an SVCDUMP with minor code
C9C212F7. The TCB that causes this dump with have the following
traceback:
bbormcdx(RMCDP_Class::RMCDP_PC_FunctionCodes,...)
RMCDP_Class::takeSVC_Dump(unsigned int)
ORBEyeCatcher::eyeCatcherNotVaild(char*,char*,unsigned int)
ORB_Request::~ORB_Request()
BBO_BOA::return_ORB_request(ORB_Request*)
ACR_ExecutionThread::ProcessXMemOutboundResponse(acrwObj*)
ACR_ExecutionThread::RemoveAndProcessWork(ThreadCleanUp*)
ACR_ExecutionRoutine

Problem conclusion

Code was added to ensure that the ORBR pointer is reset to
0 when an HTTP response fails. This prevents Java from
attempting a delete of the ORBR object.
