I2JAV11 — Java SystemException should contain nested exception field

The Java org.omg.CORBA.SystemException class should contain a nested exception
field. This would assist debugging when a Java exception occurs locally
within the client ORB when marshalling a request or unmarshalling a reply.
At present, when generic system exceptions such as COMM_FAILURE or BAD_PARAM
are returned to the application by the client ORB, it can be difficult to
identify the precise lower-level failure that caused the problem.

This issue applies specifically to system exceptions arising locally within
a Java client, not those returned by the server to the client.
