java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Java HotSpot(TM) Client VM (build 1.3.0, mixed mode)


the IDL interface SendingContext::CodeBase (defined in the OMG Objects-by-Value
spec) has code generated into the package com.sun.org.omg. The org.omg sub
package is fine but the top level packages(s) com.sun break portability. These
stubs should not appear in these packages.

The problem is compounded when an object that implements this interface is
passed as the last parameter to the readValue method of the
javax.rmi.CORBA.ValueHandler:

Serializable readValue(org.omg.CORBA.portable.InputStream, int, Class,
org.omg.SendingContext.RunTime)

The RunTime interface is the 'super class' of the CodeBase interface so it
should be perfectly valid to pass CodeBase object into this method. However. if
we generate our own stubs for codebase (in the correct package) i.e. object
implements the interface:
org.omg.SendingContext.CodeBase

a ClassCastException is thrown from the implementation if readValue. If we use
the stubs from the rt.jar (in package com.sun) then everything works ok. I
expect that a java language cast is being used instead of using a narrow method
as is correct when dealing with IDL objects (CodeBaseHelper.narrow).

This is a serious problem as it inhibits our ability to support JDKs from other
vendors. This problem also appears in JDK 1.3 for Solaris - haven't checked NT.
