BASubordinateCrashDuringComplete.txt byteman script causes a NPE exception to be thrown ---------------------------------------------------------------------------------------- Key: JBTM-1017 URL: https://issues.jboss.org/browse/JBTM-1017 Project: JBoss Transaction Manager Issue Type: Bug Security Level: Public(Everyone can see) Components: Testing, XTS Reporter: Paul Robinson Assignee: Paul Robinson Fix For: 4.17.0 Comment by Amos, which was correct: {quote} For tracing SubordinateCoordinatorCompletionParticipantStub compensate throw exceptions, there are 3 rules in BASubordinateCrashDuringComplete script. RULE trace subordinate participant stub compensate with no coordinator CLASS com.arjuna.wst11.stub.SubordinateCoordinatorCompletionParticipantStub METHOD compensate AT THROW 3 ... RULE trace subordinate participant stub compensate with unactivated coordinator CLASS com.arjuna.wst11.stub.SubordinateCoordinatorCompletionParticipantStub METHOD compensate AT THROW 4 ... RULE trace subordinate participant stub compensate with system exception from coordinator CLASS com.arjuna.wst11.stub.SubordinateCoordinatorCompletionParticipantStub METHOD compensate AT THROW 5 ... for SubordinateCoordinatorCompletionParticipantStub.java public void compensate() throws FaultedException, WrongStateException, SystemException {...} I read from byteman document which has the following describes about AT THROW: An AT THROW specifier identifies a throw operation within the trigger method as the trigger point. The throw operation may be qualified by a, possibly package-qualified, typename identifying the lexical type of the thrown exception. If a count N is supplied then the location specifies the Nth textual occurrence of a throw. If the keyword ALL is specified in place of a count then the rule will be triggered at all matching occurrences of a throw. I'm not sure about the textual occurrence of a throw. For this compensate method, AT THROW 3 => FaultedException AT THROW 4 => WrongStateException AT THROW 5 => SystemException is it right ? but the last throw rule causes NPE when the first booting jboss to run the test. I try to changes every AT THROW rule reducing one occurrence, and the test works fine. {quote}
