  Customer code was throwing a CredentialExpiredException on the
  server side which throws a ForwardRequest exception, intending
  to regenerate the credential. But customer ended up with a
  NullPointerException.
  

Local fix

Problem summary

• NPE due to Registry being set to null because the registry value
  not set before some specific call and hence the NPE in ORB
  

Problem conclusion

• This defect will be fixed in:
  5.0.0 SR11 FP2
  .
  The NPE happens in the ClientDelegate.lookupServant() method as
  a result of the SubContractRegistry being null.
  To counter the NullPointerException, changes have made to do
  this setting of registry.
  .
  To obtain the fix:
  Install build 20100123 or later
