it depends what your worker method is doing.

If you have a method that keeps allocating more
memory, than you should see the free memory decrease.
If on the other hand your worker method calls some
system methods to do some work, than the outcome is
implemenation specific. Kaffe's implementation of the
system methods could be more efficient than Sun's, and
don't require new objects to be instantiated, for
example.
