JAV2I12 — Need read_Value(clz) on InputStream

Summary: It is possible for an RMI/IDL value class to contain an IDLEntity type
that was mapped from an IDL valuetype. In this case, the GIOP
encoding of the IDLEntity type sent by an IDL/Java or C++ application
to an RMI-IIOP appplication may not contain type information (if the
actual type is the same as the declared type).

In order to allow the ValueHandler to demarshal these IDLEntity types,
an additional API call such as read_Value(Class clz) in needed on the
org.omg.CORBA.portable.InputStream class. This allows the ValueHandler
to pass the expected class (which it knows) to the InputStream.

For symmetry, a write_Value(java.io.Serializable obj, Class clz) method
should be added to org.omg.CORBA.portable.OutputStream. This would
allow RMI-IIOP marshalling to use the same optimized encoding for this
case as is possible for C++ and IDL/Java.

Closed, accepted
