The following APIs were documented in J2SE 1.3 and 1.4, but
not actually shipped in the JRE:

org.omg.CORBA.Repository
org.omg.CORBA.Initializer

These APIs are part of the Interface Repository, and are required for
supporting FulValueDescriptors as part of the codebase support that is used
to marshal valuetypes in CORBA. However, all of these APIs are actually
mapped into the com.sun.org.omg.CORBA package to avoid adding unstable
APIs to the org.omg.CORBA space, which is part of the official API
for J2SE. As a consequence, org.omg.CORBA.Repository and
org.omg.CORBA.Initializer should not be documented at all. The
fact that they were incorrectly documented in J2SE 1.3 may require
that we carry the documentation forward into J2SE 1.4, but JCKs
should not be written in J2SE 1.4 for these two interfaces.
