Alright, thanks. Looks like I wasn't up to date with gnu classpath 
itself. In this case, the problem reduces from gnu classpath and GCJ to 
GCJ only.
The main GCJ developpers are pretty much only interested in compiling 
java to shared executables on linux.
Because there's no active windows maintainer, building shared windows 
executable is currently broken.
Because no one ever looked into it, the gnu classpath AWT/Swing 
currently only works with shared executables on linux (static 
executables on linux won't work and noone ever tried gnu classpath 
AWT/Swing on windows).

That leaves me no other option than use swingWT instead of the gnu 
classpath implementation...

Yes, swingWT doesn't cover all you needs. I suggest to either work on 
swingWT (it's open source) or (what I prefer) change to SWT directly...

Ah, and thanks for reporting the bug. Looks like my parsing of the 
package from source files has a bug. I'll investigate that...
