Yes - as I said the license does have some problems.
First, it is not clear whether the license has any legal meaning at all.
It is publicly available documentation, and I don't know how they
could legally restrict someone from using it to build a clean-room
implementation. I.e. are they just permitting us to do something
we can do anyway? (And of course the legal status of reverse
engineering varies from country to country.)

There is also the all-or-nothing problem: No subsetting implies a
huge initial hurdle. I think we can reasonable interpret this as
referring to no subsetting of *indivual classes*. We can also
say that our *goal* is to implement the whole damn spec, but we
have to do one chunk at a time.

I could argue the onus is on Sun: If we don't have access to the
test-suite, we can't verify compliance. However, our *goal* is
to comply, and if any discrepencies are pointed out, we will
attempt to fix the problem, to the extent of our abilities.
