             Summary: NotSerializableException when attempting to serialize kcontext.getMatch().getObjects()
                 Key: DROOLS-345
                 URL: https://issues.jboss.org/browse/DROOLS-345
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions:  6.0.0.CR4
         Environment: Windows, Oracle Java JDK 1.7.0_21
            Reporter: Reinis Vicups
            Assignee: Mark Proctor


Optaplanner is using kcontext.getMatch().getObjects() to retrieve objects participating in the match.

This rule
rule "failing rule"
    when
        $project : Project
        $resourceParallelism : Set from accumulate( Assignment(project == $project, resource != null, $resource : resource),
            collectSet($resource) )
    then
        scoreHolder.addHardConstraintMatch(kcontext, -Math.abs($resourceParallelism.size() - $project.getOptimalResourceParallelism()));
end

cause kcontext.getMatch().getObjects() later on to return List of two elements:

1. element is instance of Project (serializable)
2. element is instance of HashMap$KeySet of Resource (serializable)

Issue is - HashMap$KeySet is not serializable thus causing the said Exception.

I checked up with Mr. Proctor and Mr. De Smet. The final assumption was that accumulate could somehow cause HashMap$KeySet to be returned.

Would be great if someone with understanding could check out how the objects get into kcontext.getMatch().getObjects() from the above rule and if it is drools wrapping my objects in HashMap$KeySet
