[rules-users] ConcurrentModificationException at org.drools.reteoo.ClassObjectTypeConf.getMatchingObjectTypes

[karthizap]

I am using Drools-core.jar(version-5.0.0.CR1) and getting the following
exception. I could see similar stacktrace reported with
JIRA-1888(https://jira.jboss.org/jira/browse/JBRULES-1888) and its marked as
closed. Fix related to this Jira is not available (Rete.java) in the Drools
5.0.1  and 5.1.0 source code/drools-core jar files. 

public void readExternal(ObjectInput in) throws IOException, 
                                            ClassNotFoundException { 
        entryPoints = Collections.synchronizedMap((Map<EntryPoint,
EntryPointNode>) in.readObject()); 
        ruleBase = ((DroolsObjectInputStream)in).getRuleBase(); 
        super.readExternal( in ); 
    }
