[jbosstools-issues] [JBoss JIRA] Updated: (JBIDE-5542) Potential NullPointerException in VPE openned on file from project without JBossTools nature

Potential NullPointerException in VPE openned on file from project without JBossTools nature -------------------------------------------------------------------------------------------- Key: JBIDE-5542 URL: https://jira.jboss.org/jira/browse/JBIDE-5542 Project: Tools (JBoss Tools) Issue Type: Bug Components: Visual Page Editor core Affects Versions: 3.1.0.CR1 Reporter: Denis Golovin Assignee: Maxim Areshkau Fix For: 3.1.0.CR2 I cannot provide exact steps to reproduce it but stack trace tells me that that might happen for any none JBossTools project. For me it happens on project with JSF capabilities. To fix this problem on JBossTools JSF project, it should be closed/opened and VPE starts working. org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:3884) at org.eclipse.swt.SWT.error(SWT.java:3799) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:137) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3468) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3115) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2405) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2369) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2221) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:500) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:493) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:194) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:368) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:559) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:514) at org.eclipse.equinox.launcher.Main.run(Main.java:1311) Caused by: java.lang.NullPointerException at org.jboss.tools.vpe.editor.bundle.BundleMap.refreshRegisteredBundles(BundleMap.java:100) at org.jboss.tools.vpe.editor.bundle.BundleMap.refresh(BundleMap.java:343) at org.jboss.tools.vpe.editor.VpeController.refreshTemplates(VpeController.java:1689) at org.jboss.tools.vpe.editor.VpeEditorPart$ActivationListener.handleActivation(VpeEditorPart.java:1075) at org.jboss.tools.vpe.editor.VpeEditorPart$ActivationListener.access$1(VpeEditorPart.java:1064) at org.jboss.tools.vpe.editor.VpeEditorPart$ActivationListener$1.run(VpeEditorPart.java:1059) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) ... 22 more
