The 4 classes discussed by IBM were inadvertantly omitted from JDK 6. These classes
are part of the official OMG specification given by the zip file ptc/00-02-01.zip, which corresponds
to the OMG specification used in JDK 6 for the IDL to Java mapping. Consequently, IBM
should use the endorsed standards mechanism to add the missing classes in their JDK,
and Sun will provide a patch to the JCK tests that includes the missing classes, which will
allow IBM to correctly pass the JCK test for Java 6.
