It seems to me that we have a versioning problem here. If the
HSX source in OpenJDK6 is not the same as the baseline HSX source,
then the HSX version number should _not_ be the same.

It might be appropriate to bump the minor version number and then
reset the build number. Something to make the HSX version identity
unique if the source code is indeed different.

Joe, this needs to be discussed with the HotSpot P-Team.
