Oh, I didn't realize that you were approaching the problem with Sun's
source.  Yes, your plan would work.  We are definitely not going to do
that, because libgcj is free software, and Sun's JDK is not.  libgcj
hackers can't even look at Sun's source.

Does it matter if someone ports the Sun's awt /swing stuff to gcj kinda of like
an addon?

Matter in what way?  I think you're free to do that.  Of course, we
couldn't distribute it.  However, JNI isn't finished yet (I'm actively
working on it, but I don't have an ETA).  So making this work would
probably be hard.

No concrete ideas yet.
We're hoping to pick up some of this as part of our merger with
Classpath, but the situation is still a bit unclear.

I haven't taken a detailed look at Sun's awt or swing stuff
however it seems almost intuitive that one should be a able
to port the JNI stuff to whatever gcj has. I assume that
in the case of gcj it will mean mapping JNI to CNI and of course
the respective c routines. Just a high level thought.

Any ideas of when will gcj support awt or swing?

I chatted with somebody once who maintains a commercial Java compiler
for Windows.  His product uses Sun's class libraries.  He said debugging
the JNI stuff for AWT was some of the hardest work he'd ever done,
because it exposed various subtleties in Sun's JNI implementation.

Not very encouraging news, in case anybody wants to attempt it.

The classpath project seems like the best way to go for AWT.  However
since Swing is pure Java, I suspect many will "borrow" it from the JDK
once AWT is working sufficiently well.
