Hi,

   I have yet problems to run the ja extension, even weaving any JDK
class... I have here a trace when weaving the standard java2demo jar..

    Any idea what could it be? How can I enabling some debug traces to
see where it fails?

    Isn't JastAdd replacing polyglot front-end? Why the exception
happens in polyglot.util ?

Cheers,

Alex
