Mario Fusco created JBRULES-3536: ------------------------------------ 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. -- This message is automatically generated by JIRA.
