[jboss-jira] [JBoss JIRA] (DROOLS-838) Random NPE using KieScanner

Random NPE using KieScanner --------------------------- Key: DROOLS-838 URL: https://issues.jboss.org/browse/DROOLS-838 Project: Drools Issue Type: Bug Affects Versions: 6.2.0.Final Environment: Centos (Linux 2.6.32-431.5.1.el6.x86_64) Reporter: Daniel Daniel Assignee: Mario Fusco Fix For: 6.3.0.Final Same stacktrace as here: https://bugzilla.redhat.com/show_bug.cgi?id=1200784 (Camel (camelContext) thread #0 - JmsConsumer[inQueue]) null: java.lang.NullPointerException at org.kie.scanner.embedder.EmbeddedPomParser.getPomDirectDependencies(EmbeddedPomParser.java:27) [kie-ci-6.2.0.Final.jar:6.2.0.Final] at org.kie.scanner.ArtifactResolver.getPomDirectDependencies(ArtifactResolver.java:59) [kie-ci-6.2.0.Final.jar:6.2.0.Final] at org.kie.scanner.ArtifactResolver.getAllDependecies(ArtifactResolver.java:64) [kie-ci-6.2.0.Final.jar:6.2.0.Final] at org.kie.scanner.KieRepositoryScannerImpl.indexAtifacts(KieRepositoryScannerImpl.java:329) [kie-ci-6.2.0.Final.jar:6.2.0.Final] at org.kie.scanner.KieRepositoryScannerImpl.setKieContainer(KieRepositoryScannerImpl.java:73) [kie-ci-6.2.0.Final.jar:6.2.0.Final] at org.drools.compiler.kie.builder.impl.KieServicesImpl.newKieScanner(KieServicesImpl.java:115) [drools-compiler-6.2.0.Final.jar:6.2.0.Final] But am using 6.2.0.Final Code is the basic use case: kServices = KieServices.Factory.get(); releaseId = kServices.newReleaseId( "com.company", "rulesBrmsRepo", "LATEST" ); kContainer = kServices.newKieContainer( releaseId ); kScanner = kServices.newKieScanner( kContainer ); // // Start the KieScanner polling the maven repository every 5 mins kScanner.start( 300000L ); Nothing particularly special about the occurrences, but once it happens, it stays broken. Occurs randomly after a few hours of working without issue. It sometimes erroneously declares that: Environment variable M2_HOME is not set though I suppose that has to do with using an internal Maven Another thing is it sometimes looks for the JAR in the plugins repo, which is only mentioned under pluginRepositories in settings.xml. Why would it look for it there?
