Local fix

• force invocations to go over the wire by deploying ejbs with
  rmic -nolocalstubs option
  

Problem summary

• For colocated invocations, the custom stream format used is 1
  which does not support enclosures.The bug was in the resetting
  these enclosures for custom streams as the customer's.
  

Problem conclusion

• This defect will be fixed in:
  5.0.0 SR12
  6.0.0 SR6
  .
  ORB has been fixed for handling this bug in custom data
  marshalling with stream format 1.
  .
  To obtain the fix:
  Install build 20100431 or later
