Juergen Zimmermann [https://community.jboss.org/people/Juergen.Zimmermann] created the discussion "javax.xml.parsers.FactoryConfigurationError: Provider __redirected.__DocumentBuilderFactory not found" To view the discussion, visit: https://community.jboss.org/message/820446#820446 -------------------------------------------------------------- I just tried Eclipse Kepler RC1 and JBoss Tools from http://download.jboss.org/jbosstools/builds/development/4.1.0.Beta1b.core... http://download.jboss.org/jbosstools/builds/development/4.1.0.Beta1b.core... . However, after doing a "Maven > Update Project", then I'm getting this stacktrace followed by a broken workspace. Broken means that when I restart Eclipse to use this workspace, then it crashes. !ENTRY org.eclipse.core.jobs 4 2 2013-05-30 17:33:24.997 !MESSAGE An internal error occurred during: "Updating Maven Project". !STACK 0 javax.xml.parsers.FactoryConfigurationError: Provider __redirected.__DocumentBuilderFactory not found at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:127) at org.eclipse.jdt.internal.core.JavaProject.decodeClasspath(JavaProject.java:912) at org.eclipse.jdt.internal.core.JavaProject.readFileEntriesWithException(JavaProject.java:2497) at org.eclipse.jdt.internal.core.JavaModelManager$PerProjectInfo.readAndCacheClasspath(JavaModelManager.java:1256) at org.eclipse.jdt.internal.core.DeltaProcessor.readRawClasspath(DeltaProcessor.java:556) at org.eclipse.jdt.internal.core.DeltaProcessor.checkProjectsAndClasspathChanges(DeltaProcessor.java:522) at org.eclipse.jdt.internal.core.DeltaProcessor.checkProjectsAndClasspathChanges(DeltaProcessor.java:536) at org.eclipse.jdt.internal.core.DeltaProcessor.checkProjectsAndClasspathChanges(DeltaProcessor.java:536) at org.eclipse.jdt.internal.core.DeltaProcessor.resourceChanged(DeltaProcessor.java:2037) at org.eclipse.jdt.internal.core.DeltaProcessingState.resourceChanged(DeltaProcessingState.java:470) at org.eclipse.core.internal.events.NotificationManager$1.run(NotificationManager.java:291) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.NotificationManager.notify(NotificationManager.java:285) at org.eclipse.core.internal.events.NotificationManager.broadcastChanges(NotificationManager.java:149) at org.eclipse.core.internal.resources.Workspace.broadcastPostChange(Workspace.java:396) at org.eclipse.core.internal.resources.Workspace.endOperation(Workspace.java:1531) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:45) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53) Caused by: java.lang.ClassNotFoundException: __redirected/__DocumentBuilderFactory at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:266) at javax.xml.parsers.FactoryFinder.getProviderClass(FactoryFinder.java:123) at javax.xml.parsers.FactoryFinder.newInstance(FactoryFinder.java:178) at javax.xml.parsers.FactoryFinder.newInstance(FactoryFinder.java:147) at javax.xml.parsers.FactoryFinder.find(FactoryFinder.java:219) at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:121) ... 17 more -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/820446#820446] Start a new discussion in JBoss Tools at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
