[jboss-jira] [JBoss JIRA] (JBRULES-3439) NPE in AbstractTabuAcceptor.stepTaken

NPE in AbstractTabuAcceptor.stepTaken ------------------------------------- Key: JBRULES-3439 URL: https://issues.jboss.org/browse/JBRULES-3439 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-planner Affects Versions: 5.4.0.Beta2 Environment: drools-planner-example 5.4.0-SNAPSHOT pulled via Maven on March 29. I believe this corresponds to https://github.com/droolsjbpm/drools-planner/commit/ba38344b7563830eb2a72... Reporter: Chris Dolan Assignee: Geoffrey De Smet Priority: Critical Fix For: 5.4.0.Final I know this is a weak bug report and I apologize in advance for that... I'm writing integration tests for my solver configuration. My code seems to work in my GUI (subclass of CommonApp) but it fails under my junit test. I'm quite new to Drools and Planner so I wouldn't be surprised if the root cause is my fault, but I think a NPE is bad news. {noformat} 2012-03-30 15:26:05,743 INFO [DefaultSolver.java:172] Solving started: time spend (25), score (-2hard/-26soft), new best score (-2hard/-26soft), random seed (0). - o.d.p.c.s.DefaultSolver 2012-03-30 15:26:05,786 DEBUG [DefaultLocalSearchSolverPhase.java:109] Step index (0), time spend (68), score (-1hard/-22soft), new best score (-1hard/-22soft), accepted move size (8) for picked step (JobSlot(s2,0) => Job(j1)). - o.d.p.c.l.DefaultLocalSearchSolverPhase 2012-03-30 15:26:05,815 DEBUG [DefaultLocalSearchSolverPhase.java:109] Step index (1), time spend (97), score (0hard/-8soft), new best score (0hard/-8soft), accepted move size (11) for picked step (JobSlot(s1,0) => Job(j2)). - o.d.p.c.l.DefaultLocalSearchSolverPhase 2012-03-30 15:26:05,831 DEBUG [DefaultLocalSearchSolverPhase.java:109] Step index (2), time spend (113), score (0hard/-4soft), new best score (0hard/-4soft), accepted move size (13) for picked step (JobSlot(s1,1) => Job(j1)). - o.d.p.c.l.DefaultLocalSearchSolverPhase 2012-03-30 15:26:05,845 DEBUG [DefaultLocalSearchSolverPhase.java:109] Step index (3), time spend (127), score (0hard/-2soft), new best score (0hard/-2soft), accepted move size (13) for picked step (JobSlot(s2,1) => Job(j2)). - o.d.p.c.l.DefaultLocalSearchSolverPhase java.lang.NullPointerException at org.drools.planner.core.localsearch.decider.acceptor.tabu.AbstractTabuAcceptor.stepTaken(AbstractTabuAcceptor.java:163) at org.drools.planner.core.localsearch.decider.DefaultDecider.stepTaken(DefaultDecider.java:167) at org.drools.planner.core.localsearch.DefaultLocalSearchSolverPhase.stepTaken(DefaultLocalSearchSolverPhase.java:107) at org.drools.planner.core.localsearch.DefaultLocalSearchSolverPhase.solve(DefaultLocalSearchSolverPhase.java:71) at org.drools.planner.core.solver.DefaultSolver.runSolverPhases(DefaultSolver.java:181) at org.drools.planner.core.solver.DefaultSolver.solve(DefaultSolver.java:150) {noformat}
