[abc-users] weaver sensitive to class order in .jar ?

Hi,
     While trying to weave JDK classes, I found a curious behavior of
the weaver...

     It fails depending on the order of the classes in the jar... In
this example, if Object is in second position it fails, but if it's in
first position it works fine.

     Is there a workaround for this issue? This time, as proposed by
Pavel, I was able to weave with -ext abc.ja independently of the
order, but the extension fails when I try to weave bigger subsets of
the JDK...

  Many thanks,

Alex
