Yes.  I just did a CVS update to get the latest stuff and we still have
this problem.

I wrote a standalone sample program that duplicates the problem.  Run
JSSupport and you should get this exception:

defineClass org.mozilla.javascript.gen.c2
Exception in thread "main" java.lang.NoClassDefFoundError:
