Sorry Tim, I assumed that code in the GPL'd class libs migrated into
the custom version which you sold and therefore you'd have to require
it. Thanks for the clarification. I should have researched this more.

Going back to the beginning of Classpath when we discussed licensing,
the problem with releasing the class libraries as GPL is the GPL
doesn't allow one to 'link' proprietary code to those libraries either
at compile time or runtime. According to what I've heard in the past,
I believe even from RMS himself, the VM in essence performs this
'link' because without those GPL'd libraries the program could not
function. Because the VM itself is self-contained, it could (and
should to protect it) be distributed under the GPL. That's what I
didn't like about Japhar switching from GPL licensing to LGPL, but I
understand why the developers of Japhar wanted to do it and that's ok.
If I've screwed up any of that recollection Paul, Aaron, just say so.
