I2JAV11 — Discriminated Union value issue

Summary: An IDL Discriminated Union has a discriminator of some type. The
discriminator is permitted to take any value allowed by its type -
nothing in the CORBA spec constrains the discriminator"s value to be
those of the branch labels present in the union or just one catch-all
default. For this reason, CORBA 2.2, section 3.8.2 defines a Discriminated
Union"s value as follows: <example>So, if I were to create a foo and set the discriminator to 74, someone
receiving this instance from me should be able to discern that the
discriminator"s value was set to 74.

As it stands, the IDL->Java mapping provides for discovering the value
of the discriminator, so if some other ORB sent me a foo with the
discriminator set to 74 I could discern this, but as far as I can tell
from reading the current IDL->Java mapping (CORBA 2.2 - no relevant
changes appear to be present on orbos/98-03-10) there is no way that I
could set the discriminator"s value to 74.
