When we fixed the jmx bug 6696028, we expected to receive "RemoteException" as thrown by the current existing JDK6 (for example 1.6.0_10), but we got NullPointerException from the 6u12.

This possibly impacts other existing applications, so important to run JCK to verify the compability.

Here is the test:
/*

 * @bug 6696028
 * @summary JMXServiceURL like service:jmx:rmi:///jndi/iiop:// should be
 * rejected by the RMI conn provider.

N/A

I'm not sure that this is an ORB bug.  What I see in the 6u10 traceback is clear
evidence that an operation was performed on the ORB AFTER the ORB was shutdown.
That is clearly illegal, and points to a possible error in either the test or the
RMIConnector code.

I recently worked with Kevin Walls to get a number of memory leak fixes into the
JDK 6u12 ORB for bug 6725987.  One result of these changes is that the exceptions thrown
by code performing operations on a destroyed ORB may change (and note that this
is unspecified behavior: there are no defined semantics for performing operations
on a destroyed ORB instance).

I'd like to find out a few things from people knowledgable about RMIConnector and
the specific JCK tests:

1. Does the test explicitly create an ORB for use in the RMIConnector?  If so,
   exactly how does the test destroy the ORB?  For example, calling ORB.destroy in
   a finally block, then performing operations on the ORB after the finally block
   is illegal and will result in unspecified behavior.

2. Is there something in the RMIConnector code that could be causing the ORB.destroy 
   call?  I did not find it immediately, but I am not familiar with that code.

Here is the answer on the first Ken's question. The tests don't explicitly create an ORB for use in the RMIConnector. All tests mentioned in the bug report are similar. Here is a direct link to one of the test sources:

After backing out 6725987 and 6773533 from 6u12-b03 master ws, this issue is resolved.

Most of the affected tests are present in JCK 1.5a, but they passes without a 
single exception for jdk 1.5.0_17 b07 and for 1.5.0_16 b12.

IllegalIIOPURLTest.java makes a Runtime.exec call to start orbd.  But the connection failure exceptions all happen because the orbd is not yet responding.

Thread.sleep(3000) after the Runtime.exec calls makes it always run reliably for me.
