I'm pretty sure it's something to do with my config or compile/run commands, 
but since I've never really used GCJ/GIJ I'm a bit lost. I used this to 
compile:

gcj -C -classpath ${CLASSPATH} ScribbleWindow.java

and this to run:

gij -classpath ${CLASSPATH} ScribbleWindow

but got this error:

Exception in thread "main" java.lang.VerifyError: verification failed at PC 2
