I don't know that the current port has undergone enough stress testing to
have a proper indication of its stability. For that reason alone I'd have
to guess the current Blackdown version is more stable.

The current patchset will build cleanly, however its missing a critical
piece of functionality for 4.0 and 5.0. Expect this functionality to be
present in the next patchset though (thanks Steve!) which will almost
certainly be termed "alpha".

To answer the first question:
Advantage: Its much easier to do JNI with a native port.
Disadvantage: The Blackdown port has been tested much more thoroughly and
includes a JIT (you need to compile a 3rd party JIT with
the current FreeBSD patches -- if you want one that is).
In terms of your second question, it depends upon the ports in question.

Can't comment on these :).

Only Apple can answer this :). I don't know how beneficial the current
port would be towards a port of their own.
