Hi,
It never rains it pours!
Given a very simple rule:-
package drools.debug
rule "Test1"
when
$m : Machine ( )
then
System.out.println("--> DEBUG!");
end
Throws a very unfriendly error:-
Exception in thread "main" java.lang.VerifyError: (class:
drools/debug/MachineShadowProxy, method: setProperty signature:

The Machine Class does extend another that has assessors for a Class
that has lots and lots of constructors...
Complete, self contained JAR, file available on request (a new JIRA?)
Thanks,
Mike
