## org.omg.CORBA
Class UNKNOWN

    java.lang.Object
      java.lang.Throwable
          java.lang.Exception
              java.lang.RuntimeException
                  org.omg.CORBA.SystemException
                      org.omg.CORBA.UNKNOWN

All Implemented Interfaces:
  Serializable

public final 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.)

It contains a minor code, which gives more detailed information about what caused the exception, and a completion status. It may also contain a string describing the exception.

See the section Minor Code Meanings to see the minor codes for this exception.
