             Summary: NPE in DefaultHardAndSoftScore.compareTo()
                 Key: JBRULES-3532
                 URL: https://issues.jboss.org/browse/JBRULES-3532
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-eclipse (expert)
    Affects Versions: 5.4.0.Final
            Reporter: Martin Vecera
            Assignee: Mark Proctor


When running a benchmark on a very slow machine (virtual machine), hard and soft part of the score might remain uninitialized for long time (might be related to JBRULES-3317). This discovered an issue in the compareTo() method.

Caused by: java.lang.NullPointerException
