[jenk...@corsix.org (JIRA)]

Peter Cawley created JENKINS-23315 NPE at hudson.plugins.im.tools.BuildHelper.isFix Issue Type: Bug Assignee: kutzi Components: instant-messaging Created: 04/Jun/14 3:04 PM Description: We're observing the following NPE, which is causing builds to spuriously fail: 18:21:55 FATAL: null 18:21:55 java.lang.NullPointerException 18:21:55 at hudson.plugins.im.tools.BuildHelper.isFix(BuildHelper.java:69) 18:21:55 at hudson.plugins.im.build_notify.SummaryOnlyBuildToChatNotifier.buildCompletionMessage(SummaryOnlyBuildToChatNotifier.java:34) 18:21:55 at hudson.plugins.im.IMPublisher.notifyChatsOnBuildEnd(IMPublisher.java:577) 18:21:55 at hudson.plugins.im.IMPublisher.notifyOnBuildEnd(IMPublisher.java:304) 18:21:55 at hudson.plugins.im.IMPublisher$1.endBuild(IMPublisher.java:718) 18:21:55 at hudson.matrix.MatrixBuild$MatrixBuildExecution.post2(MatrixBuild.java:407) 18:21:55 at hudson.model.AbstractBuild$AbstractBuildExecution.post(AbstractBuild.java:658) 18:21:55 at hudson.model.Run.execute(Run.java:1731) 18:21:55 at hudson.matrix.MatrixBuild.run(MatrixBuild.java:306) 18:21:55 at hudson.model.ResourceController.execute(ResourceController.java:88) 18:21:55 at hudson.model.Executor.run(Executor.java:231) 18:21:55 at hudson.model.OneOffExecutor.run(OneOffExecutor.java:43) The line reported by the tip of the stack trace would seem to be the middle return statement in the following: @Deprecated public static boolean isFix(AbstractBuild<?, ?> build) { if (build.getResult() != Result.SUCCESS) { return false; } AbstractBuild<?, ?> previousBuild = getPreviousNonAbortedBuild(build); if (previousBuild != null) { return previousBuild.getResult().isWorseThan(Result.SUCCESS); } return false; } The job in question is configured to allow multiple concurrent builds, at which point it seems plausible that previousBuild ends up being set to a build that is still in progress, causing getResult to return null.
