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: (Ljava/lang/String;JLjava/lang/String;)V) Register 3 contains wrong type

The Machine Class does extend another that has assessors for a Class that has lots and lots of constructors...

Complete re-producible JAR attached.
