I don't think the point was about different free software licenses at all. That is as you say just a choice of preference of which free software license a community choices to use as default. In general free software hackers seem pretty open minded about these things in my experience. > Just because we don't play > exactly in your world doesn't mean there is a trap.

It certainly seems a lesser trap, since it only impacts users of systems like solaris and windows that are already non-free. But we now do have OpenJDK and we do want it to be truly free for all users. It is questionable whether Windows will ever be completely liberated (but it might happen ultimately trough Wine and cygwin/mingw). But for OpenSolaris it seems within reach right now, if we wouldn't be relying on a proprietary toolchain on that platfrom. I agree with Andrew that using a proprietary compiler instead of a free one (whether that is distributed under a BSD, GPL or Apache style license) seems like trouble in the long run. It is ultimately the same kind of trap if you are relying on extensions of a proprietary toolchain, then you are not giving your users real freedom. If at all possible, and if we can find volunteers to do it of course, it would be beneficial to use a free toolchain on all platforms that OpenJDK support imho. Cheers, Mark
