- * The org.omg.CORBA.portable.UnknownException is used for reporting
- * unknown exceptions between ties and ORBs and between ORBs and stubs.
- * It provides a Java representation of an UNKNOWN system exception
- * that has an UnknownExceptionInfo service context.
- * If the CORBA system exception org.omg.CORBA.portable.UnknownException
- * is thrown, then the stub does one of the following:
- * (1) Translates it to org.omg.CORBA.UNKNOWN.
- * (2) Translates it to the nested exception that the UnknownException contains.
- * (3) Passes it on directly to the user.
