EffectsPlayground sample fails to launch with javafx1.0-integration build #336, which contains Richard's performance changes:
http://jfx.sfbay.sun.com/hudson/job/javafx1.0-integration/changes

I've verified that it works okay with build #335, but fails with #336. Tried only on Mac OS X with JDK 5 so far.

Full exception attached. You can run EffectsPlayground as an applet here:
http://jfxsamples.sfbay.sun.com/EffectsPlayground/description.html

Or open the project from the install/samples/EffectsPlayground directory.
