That should work! ;)

I think that should fail - however the reverse should be possible. (ie run a
1.0.1 in a 1.0.0 environment).
Remembering that a minor version does not make any binary incompatible
changes or any changes to semantics. (Just docco fixxes and added forward
compatible features).

You mean something like MyWorker.VERSION - that should be workable.

Thats one way of doing it. Another is to actually implement proper
ClassLoaders that follow the jdk1.3 spec with respect to package dependencies
and version interfaces at package level.
