Which version of RAP are you using? With the introduction of "org.eclipse.rap.rwt.osgi" bundle in 1.5 a lot of code has been changed there. This bug also occurs with RAP 1.5M6. Arian, there is no more call too applicationLauncherTracker.close() in HttpServiceTracker.close(). Could you attach a stack trace from the NPE with 1.5M6? Hi Ivan, here it is: org.osgi.framework.BundleException: Exception in org.eclipse.ui.internal.WorkbenchPlugin.stop() of bundle org.eclipse.rap.ui.workbench. at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop(BundleContextImpl.java:791) at org.eclipse.osgi.framework.internal.core.BundleHost.stopWorker(BundleHost.java:510) at org.eclipse.osgi.framework.internal.core.AbstractBundle.suspend(AbstractBundle.java:566) at org.eclipse.osgi.framework.internal.core.Framework.suspendBundle(Framework.java:1207) at org.eclipse.osgi.framework.internal.core.StartLevelManager.decFWSL(StartLevelManager.java:592) at org.eclipse.osgi.framework.internal.core.StartLevelManager.doSetStartLevel(StartLevelManager.java:257) at org.eclipse.osgi.framework.internal.core.StartLevelManager.shutdown(StartLevelManager.java:215) at org.eclipse.osgi.framework.internal.core.InternalSystemBundle.suspend(InternalSystemBundle.java:284) at org.eclipse.osgi.framework.internal.core.Framework.shutdown(Framework.java:693) at org.eclipse.osgi.framework.internal.core.Framework.close(Framework.java:600) at org.eclipse.core.runtime.adaptor.EclipseStarter.shutdown(EclipseStarter.java:398) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:198) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386) Caused by: java.lang.NullPointerException at org.eclipse.rap.ui.internal.servlet.HttpServiceTracker.close(HttpServiceTracker.java:111) at org.eclipse.ui.internal.WorkbenchPlugin.stop(WorkbenchPlugin.java:1340) at org.eclipse.osgi.framework.internal.core.BundleContextImpl$2.run(BundleContextImpl.java:771) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop(BundleContextImpl.java:764) ... 19 more Root exception: java.lang.NullPointerException at org.eclipse.rap.ui.internal.servlet.HttpServiceTracker.close(HttpServiceTracker.java:111) at org.eclipse.ui.internal.WorkbenchPlugin.stop(WorkbenchPlugin.java:1340) at org.eclipse.osgi.framework.internal.core.BundleContextImpl$2.run(BundleContextImpl.java:771) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop(BundleContextImpl.java:764) at org.eclipse.osgi.framework.internal.core.BundleHost.stopWorker(BundleHost.java:510) at org.eclipse.osgi.framework.internal.core.AbstractBundle.suspend(AbstractBundle.java:566) at org.eclipse.osgi.framework.internal.core.Framework.suspendBundle(Framework.java:1207) at org.eclipse.osgi.framework.internal.core.StartLevelManager.decFWSL(StartLevelManager.java:592) at org.eclipse.osgi.framework.internal.core.StartLevelManager.doSetStartLevel(StartLevelManager.java:257) at org.eclipse.osgi.framework.internal.core.StartLevelManager.shutdown(StartLevelManager.java:215) at org.eclipse.osgi.framework.internal.core.InternalSystemBundle.suspend(InternalSystemBundle.java:284) at org.eclipse.osgi.framework.internal.core.Framework.shutdown(Framework.java:693) at org.eclipse.osgi.framework.internal.core.Framework.close(Framework.java:600) at org.eclipse.core.runtime.adaptor.EclipseStarter.shutdown(EclipseStarter.java:398) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:198) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386) Arian, this stack trace does not fit to 1.5M6. Probably, it is from 1.5M5. Could you check again with 1.5M6 and attach a stack trace against 1.5M6? We did some changes/refactorins related to service tracker in M6. Hi Ivan, I'm sorry, you are totally right! I was running RAP 1.5M5. With M6 it works fine. Thanks for your advice! (In reply to comment #6) > With M6 it works fine. Fixed in 1.5M6 by the re-factorings did in HttpServiceTracker. |
Build Identifier: I've got the following situation: Plug-in A depends on "org.eclipse.rap.ui" which depends on "org.eclipse.rap.ui.workbench". I've written some JUnit-Tests for Plug-in A which are summarized in a Plug-in B. So this depends on A. The tests themselfs are running without problems. But everytime a NullPointerException is thrown. I could locate and solve the problem like this: The Exception occurs on invoking the HttpServiceTracker.close(). (org.eclipse.rap.ui.internal.servlet) Especially on the following lines: === #108 - #115 public void close() { super.close(); httpContextTracker.close(); ApplicationLauncherTracker.close(); <------- } === I've solved the problem very simple but it works: === public void close() { super.close(); httpContextTracker.close(); if(ApplicationLauncherTracker != null) { ApplicationLauncherTracker.close(); } } === I suggest a similar default implementation. Reproducible: Always
