             Summary: NPE adding a null key to a TreeMap with JDK7
                 Key: JBRULES-3536
                 URL: https://issues.jboss.org/browse/JBRULES-3536
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Mario Fusco
            Assignee: Mario Fusco


The following tests throw NPE:

org.drools.verifier.data.VerifierDataMapsTest.testSaveVerifierComponentAndGetForAllComponentTypes
org.drools.verifier.data.VerifierDataMapsTest.testSaveVerifierComponentAndGetForAllFields
org.drools.verifier.data.VerifierDataMapsTest.testSaveVerifierComponentAndGetForAllRestrictions
org.drools.verifier.data.VerifierDataMapsTest.testSavePatternAndGet

java.lang.NullPointerException
	at java.util.TreeMap.compare(TreeMap.java:1188)
	at java.util.TreeMap.put(TreeMap.java:531)
	at org.drools.verifier.data.VerifierDataMaps.add(VerifierDataMaps.java:162)
	at org.drools.verifier.data.VerifierDataMapsTest.saveVerifierComponentAndGet(VerifierDataMapsTest.java:321)
	at org.drools.verifier.data.VerifierDataMapsTest.testSaveVerifierComponentAndGetForAllComponentTypes(VerifierDataMapsTest.java:105)

All the tests in class fail with similar exception. From the test, it seems that objects added to the map are not null and their values used in compareTo() are not null either. This happens only with Sun JDK 7.
