CoreException thrown when opening .class file

Hi,

I've installed and configured the plugin, but I'm
unable to open any class files. Eclipse returns an
error -- unable to open an editor window, and gives a
stack trace (attached). JAD is installed an and
working. I am using Eclipse 3.1.0.

Thanks and regards,
Michael (misha.penkov@gmail.com)
