[rules-users] Upgrading to 4.0.4

[Narendra Valada]

Hi,

I am upgrading to Drools 4.0.4 and I am getting this exception when
executing this rule:

rule "insert iterator"
when
 somecondition
then
 insert(Arrays.asList(some array).iterator());
end

Here is the exception. Is this a bug? Disabling shadow copy is not really an
option for this application.

Exception in thread "pool-1-thread-1" java.lang.IllegalAccessError: class
org.drools.shadow.java.util.AbstractList$ItrShadowProxy cannot access its
superclass java.util.AbstractList$Itr
