Local fix

Problem summary

  • A ClassCast Exception is seen when a method is invoked on the
    tie. It's a multi thread client test which makes multiple EJB
    calls on the server.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    .
    It is caused by a popLUDCL() call being missed out. The skipping
    of the popLUDCL() causes a stale LUDCL to be left over in the
    thread local stack causing problems while invoking the tie. The
    tie is expected to be loaded by a thread context classloader,
    but instead is loaded by a stale LUDCL.
