javax.rmi.CORBA.Util.isLocal(stub) restricts custom ORB

Hello All,

My ISV experienced one problem related to Sun CORBA Util Implementation
I tested it under jdk1.3, it works fine
but it fails on jdk1.4.2.

For test on jdk1.3 you need some jar files from ISV(or me) and some jar files
from j2sdk1.4.2/jre/lib

For test on jdk1.4 you only need some jar files from ISV(or me)
you will see a ClassCastException. it seems customer implemented Stub class
is not accept by javax.rmi.CORBA.Util.isLocal(Stub stub) method on jdk1.4.2
although it works fine on jdk1.3.
