All Implemented Interfaces:

public class UNKNOWN
extends SystemException

This exception is raised if an operation implementation throws a non-CORBA exception (such as an exception specific to the implementation's programming language), or if an operation raises a user exception that does not appear in the operation's raises expression. UNKNOWN is also raised if the server returns a system exception that is unknown to the client. (This can happen if the server uses a later version of CORBA than the client and new system exceptions have been added to the later version.)
