NullPointerException in VFSUtils.readManifest during WAR deployment ------------------------------------------------------------------- Key: JBAS-5178 URL: http://jira.jboss.com/jira/browse/JBAS-5178 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Components: Deployment services Affects Versions: JBossAS-5.0.0.Beta3 Environment: * Java VM: Java HotSpot(TM) Server VM 1.6.0_03-b05,Sun Microsystems Inc. * OS-System: Windows XP 5.1,x86 Reporter: David Bernstein Assigned To: Dimitris Andreadis I have a very simple WAR file that I'm trying to deploy on JBoss 5.0.0.Beta3. I'm using: * Java VM: Java HotSpot(TM) Server VM 1.6.0_03-b05,Sun Microsystems Inc. * OS-System: Windows XP 5.1,x86 I am using the -Dsun.lang.ClassLoader.allowArraySyntax=true option for the JVM for Java 6 with JBoss 5 as described in JBAS-4491. Intermittently, when I deploy the WAR file, I get a NullPointerException in org.jboss.virtual.VFSUtils.readManifest(): 2008-01-24 18:48:53,624 DEBUG [org.jboss.deployers.plugins.main.MainDeployerImpl] Add deployment: vfsfile:/C:/java/jboss/jboss-5.0.0.Beta3/server/orgmob/deploy/orgmobilist.war 2008-01-24 18:48:53,624 DEBUG [org.jboss.deployers.plugins.main.MainDeployerImpl] Removing previous deployment: vfsfile:/C:/java/jboss/jboss-5.0.0.Beta3/server/orgmob/deploy/orgmobilist.war 2008-01-24 18:48:53,624 DEBUG [org.jboss.deployers.plugins.main.MainDeployerImpl] Scheduling undeployment: vfsfile:/C:/java/jboss/jboss-5.0.0.Beta3/server/orgmob/deploy/orgmobilist.war parent=null 2008-01-24 18:48:53,624 WARN [org.jboss.system.server.profileservice.hotdeploy.HDScanner] Scan failed org.jboss.deployers.spi.DeploymentException: Error populating deployment vfsfile:/C:/java/jboss/jboss-5.0.0.Beta3/server/orgmob/deploy/orgmobilist.war at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.deployers.structure.spi.helpers.AbstractStructureBuilder.populateContext(AbstractStructureBuilder.java:77) at org.jboss.deployers.structure.spi.helpers.AbstractStructuralDeployers.determineStructure(AbstractStructuralDeployers.java:89) at org.jboss.deployers.plugins.main.MainDeployerImpl.determineStructure(MainDeployerImpl.java:743) at org.jboss.deployers.plugins.main.MainDeployerImpl.addDeployment(MainDeployerImpl.java:280) at org.jboss.deployers.plugins.main.MainDeployerImpl.addDeployment(MainDeployerImpl.java:237) at org.jboss.system.server.profileservice.hotdeploy.HDScanner.scan(HDScanner.java:270) at org.jboss.system.server.profileservice.hotdeploy.HDScanner.run(HDScanner.java:221) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:98) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:181) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:205) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.NullPointerException at org.jboss.virtual.VFSUtils.readManifest(VFSUtils.java:208) at org.jboss.virtual.VFSUtils.getManifest(VFSUtils.java:187) at org.jboss.virtual.VFSUtils.addManifestLocations(VFSUtils.java:106) at org.jboss.deployers.vfs.plugins.structure.VFSStructureBuilder.applyContextInfo(VFSStructureBuilder.java:155) at org.jboss.deployers.structure.spi.helpers.AbstractStructureBuilder.populateContext(AbstractStructureBuilder.java:73) ... 15 more <<< Sometimes it works without complaint. I haven't been able to figure out exactly which conditions tickle this. I had suspicions that it might have to do with whether it was a hot deploy or on the existence of the properties file, but I wasn't able to prove it consistently. It did seem that if there was previously no properties file and I then did a hot deploy with a properties file, then I got the exception. I was able to deploy successfully to 4.2.2.GA.
