JDK-6360330 - NullPointerException from a generated stub: no state check or synchronization protection
Description
An operation on a JMX iiop connector may get a NullpointerException because of a synchronization problem from the IIOP implementation: 6360330 

For example, when testing our event service, we got:
    [exec] STDERR:
    [exec] java.lang.NullPointerException

Comments
EVALUATION This is most likely a duplicate of 7091388. CDROutputStream is closed out too early causing a null pointer reference. The submitter can reopen if 7091388 fix doesn't solve the issue.

EVALUATION We need to wait 6360330 fix from iiop team.
