First of all, note that this bug is very linked to bug 6614506 :
   jmx interop regression when Server is over JDK6 and Client over JDK5

Indeed, the problem concerns a remote call to getMBeanInfo using rmi/iiop.
The particularity of this test failure compared to bug 6614506 is that :
1) only model MBean is concerned
2) the test fails for all interop configuration, that is :
- server runs on JDK5 and client on JDK6
- server runs on JDK6 and client on JDK5

For these reasons, I prefer to create another bug.
Then close it as duplicated if needed.

N/A

The problem may be related to the addition of readObject methods to javax.management.MBeanInfo and .MBeanFeatureInfo with the addition of Descriptors to each.  The method readObject(ObjectInputStream in) starts by doing in.defaultReadObject() and then reads a byte using in.read().  If the object being deserialized comes from JDK 5 then there was no writeObject, which means that in.read() should return -1 for EOF.  And it does do that with RMI/JRMP.  But with RMI/IIOP apparently it gets deeply confused.  You can make the problem go away by testing in.available() > 0 in these methods, and deleting the useless readObject() methods in the various ModelMBean*Info classes.  But you also have to delete ModelMBeanInfoSupport.readObject(), and that method is not useless, so this is not an acceptable fix.

Reassigning to the category for RMI/IIOP serialization, since this is clearly not a bug in the JMX code.

I'm not sure at this point.

Good, that should provide a much simpler test case.  Do you have writeObject
methods defined in cases 2 or 3?

Thanks for the info.  I'll update the corba.evolve test to include the extra cases.

Will this be fixed for both 1.5 and 1.6? When is it expected to get fixed?

Thanks for the reply.

If this takes eight months to get put into the correct category, one can imagine how long it might take before it gets fixed. :)
