It doesn't have that option...:

I've got gcj34 too, as you can see above. I'm trying to run a simple
Swing example (just creates a JFrame) but it's not working either :(
It compiles, but when i try to run, I get this:

-------------------

------------------

Could it be because JFrame is child of Frame, which is an AWT
component? Dunno...

Thank you,
