[rules-users] Possible bug

Hello, we are using official 5.0 release and sometimes (very rarely) we get following error: java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:793) at java.util.HashMap$ValueIterator.next(HashMap.java:822) at org.drools.reteoo.ClassObjectTypeConf.getMatchingObjectTypes(ClassObjectTypeConf.java:171) at org.drools.reteoo.ClassObjectTypeConf.getObjectTypeNodes(ClassObjectTypeConf.java:163) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:143) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1046) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1001) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:788) at org.drools.process.command.InsertObjectCommand.execute(InsertObjectCommand.java:22) at org.drools.process.command.InsertObjectCommand.execute(InsertObjectCommand.java:7) at org.drools.runtime.impl.BatchExecutionImpl.execute(BatchExecutionImpl.java:23) at org.drools.runtime.impl.BatchExecutionImpl.execute(BatchExecutionImpl.java:9) at org.drools.impl.StatelessKnowledgeSessionImpl.execute(StatelessKnowledgeSessionImpl.java:225) at org.fornax.cartridges.sculptor.framework.drools.DroolsAdvice.applyCompanyPolicy(DroolsAdvice.java:150) We are using AspectJ advice for starting rule evaluation for every service call.
