Mark Struberg commented on SUREFIRE-863: ---------------------------------------- How to reproduce: I did hit this problem when updating Apache DeltaSpike from surefire-2.11 to 2.12. $> git clone https://git-wip-us.apache.org/repos/asf/incubator-deltaspike.git $> cd incubator-deltaspike/deltaspike $> mvn clean install -PWeld -Dweld.version=1.1.4.Final -Dmaven.surefire.plugin.version=2.13-SNAPSHOT The funny thing is that the same project works with another container (just remove the -PWeld and you'll get OpenWebBeans as CDI container) and even with another version of Weld. Compiling with -Dweld.version=1.1.5.Final works, but 1.1.7.Final is broken again. > NPE in ConcurrentReporterManager > -------------------------------- > > Key: SUREFIRE-863 > URL: https://jira.codehaus.org/browse/SUREFIRE-863 > Project: Maven Surefire > Issue Type: Bug > Components: Junit 4.x support > Affects Versions: 2.12 > Reporter: Mark Struberg > > I have a wird NPE in surefire with one of my projects: > Caused by: java.lang.NullPointerException > at > java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:768) > at > org.apache.maven.surefire.junitcore.ConcurrentReporterManager.getTestSet(ConcurrentReporterManager.java:157) > at > org.apache.maven.surefire.junitcore.ConcurrentReporterManager.getOrCreateTestMethod(ConcurrentReporterManager.java:127) > at > org.apache.maven.surefire.junitcore.ConcurrentReporterManager.testError(ConcurrentReporterManager.java:83) > at > org.apache.maven.surefire.common.junit4.JUnit4RunListener.testFailure(JUnit4RunListener.java:110) > at > org.junit.runner.notification.RunNotifier$4.notifyListener(RunNotifier.java:100) -- This message is automatically generated by JIRA.
