You should insert
Collections.synchronizedMap(new HashMap());
Instead of new HashMap()
This error is a java error, not a drools one, it only means that two threads are, at the
same time, accessing/modifying the same Map.
The reason for this depends of your project

Maybe yes, advice is generic but I looked at source code and from what
I see iteration is going through some internal cache which is maybe
concurrently modified not through items of my Hash.
for ( ObjectTypeNode node : ruleBase.getRete().getObjectTypeNodes(
this.entryPoint ).values() ) {
Anyway modifying fact will be wrong idea ;-).

Pavel,
This is a bug. It was fixed last week:
https://jira.jboss.org/browse/JBRULES-2556
When you say you are using the "official" 5.0 version, do you mean the
Red Hat supported version or the community version? If you are a Red Hat
subscriber, you can ask them to provide you with a patch.
