I'm getting this error (see attached bug1.txt):
java.lang.Error: Unknown icode : 127 @ pc : 27

I think this is triggered by the JS call:
g.drawImage(bgImg,0,0,Color.white,null);

See the attached output and JS file.

Problem was caused by use of 'super' keyword - which has been reserved but not
implemented by Javascript. Unfortunately the keyword wasn't being error'd but
had turned into an illegal PRIMARY node.
