Then the agent would be wrong. :-)

If the agent is smart enough to ask the new version, then it should
be allowed to use that new version. By restricting JDK6 to version 1.1,
you would be precluding a tool vendor from having a single binary that
could work on JDK5, JDK6 and JDK7 where HSX is in place.
