looking at that stacktrace, you may have a point :-)   

Or rather, Sun decided that an extra buffering was the way to go. 

However, rubberbanding is quite smooth on the JDK, and jfig can open and
redraw typical files at over 20 "frames per second". That is fast enough 
for most cases.

I still don't see how classpath ends up overwriting my component, but
I haven't tested your latest patches yet.
