             Summary: Drools 7.3.0 serialization null pointer exceptions with sliding windows
                 Key: DROOLS-2210
                 URL: https://issues.jboss.org/browse/DROOLS-2210
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 7.3.0.Final
            Reporter: Manjunath S Paramesan
            Assignee: Mario Fusco
            Priority: Critical


We have a fairly large rule-base with temporal reasoning and sliding windows. 

While serializing the drools session we observe random null pointer exceptions as see below:

Exception in thread "pool-92-thread-98" java.lang.NullPointerException
