[rules-users] Upgrading to 4.0.4

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 at java.lang.ClassLoader.defineClass1(*Native Method*) at java.lang.ClassLoader.defineClass(Unknown Source) at org.drools.rule.MapBackedClassLoader.fastFindClass(* MapBackedClassLoader.java:60*) at org.drools.rule.MapBackedClassLoader.loadClass(*MapBackedClassLoader.java :79*) at java.lang.ClassLoader.loadClass(Unknown Source) at org.drools.reteoo.Rete$ClassObjectTypeConf.loadOrGenerateProxy(*Rete.java :547*) at org.drools.reteoo.Rete$ClassObjectTypeConf.defineShadowProxyData(* Rete.java:494*) at org.drools.reteoo.Rete$ClassObjectTypeConf.<init>(*Rete.java:461*) at org.drools.reteoo.Rete.assertObject(*Rete.java:152*) at org.drools.reteoo.ReteooRuleBase.assertObject(*ReteooRuleBase.java:192*) at org.drools.reteoo.ReteooWorkingMemory.doInsert(*ReteooWorkingMemory.java :71*) at org.drools.common.AbstractWorkingMemory.insert(* AbstractWorkingMemory.java:909*) at org.drools.common.AbstractWorkingMemory.insert(* AbstractWorkingMemory.java:881*) at org.drools.base.DefaultKnowledgeHelper.insert(* DefaultKnowledgeHelper.java:67*) at org.drools.base.DefaultKnowledgeHelper.insert(* DefaultKnowledgeHelper.java:61*) Thanks, Narendra Valada
