Build Identifier: M20100909-0800 1. download and untar eclipse-SDK-3.6.1-linux-gtk.tar.gz 2. start eclipse by ./eclipse -clean -data ../workspace -showlocation -vmargs -Xmx708M 3. Window->Open Perspective -> sometimes this succeeds. somethme nothing happens and I get the following in .log. At such times, "File->Exit" also becomes nonresponsive and I can't exit Eclipse. org.eclipse.core.commands.ExecutionException: No activeWorkbenchWindow found while executing org.eclipse.ui.perspectives.showPerspective at org.eclipse.ui.handlers.HandlerUtil.noVariableFound(HandlerUtil.java:40) at org.eclipse.ui.handlers.HandlerUtil.getVariableChecked(HandlerUtil.java:89) at org.eclipse.ui.handlers.HandlerUtil.getActiveWorkbenchWindowChecked(HandlerUtil.java:210) at org.eclipse.ui.handlers.ShowPerspectiveHandler.execute(ShowPerspectiveHandler.java:47) at org.eclipse.ui.internal.handlers.HandlerProxy.execute(HandlerProxy.java:293) at org.eclipse.core.commands.Command.executeWithChecks(Command.java:476) at org.eclipse.ui.internal.handlers.HandlerService.executeCommand(HandlerService.java:178) at org.eclipse.ui.internal.handlers.SlaveHandlerService.executeCommand(SlaveHandlerService.java:247) at org.eclipse.ui.actions.PerspectiveMenu.runOther(PerspectiveMenu.java:376) at org.eclipse.ui.actions.PerspectiveMenu$3.runWithEvent(PerspectiveMenu.java:130) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:584) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:501) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:411) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1258) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3540) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3161) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) 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:369) 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:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) Reproducible: Sometimes

I see the same error when I use eclipse-SDK-3.6RC4-linux-gtk (instead of eclipse-SDK-3.6.1-linux-gtk) and java 1.5(jrockit-R27.1.0-jdk1.5.0_08). I haven't seen the error on EL5 so far. nhxlc200 10>uname -a Linux nhxlc200 2.6.18-8.el5PAE #1 SMP Fri Jan 26 14:28:43 EST 2007 i686 i686 i386 GNU/Linux
I tried this on another system that has the identical OS Linux anothersystem 2.6.32-71.el6.i686 #1 SMP Wed Sep 1 01:26:34 EDT 2010 i686 i686 i386 GNU/Linux and can not reproduce this problem. In case you can't either, any clue on what may be wrong (with the system) would be helpful.
(In reply to comment #3) > In case you can't either, any clue on what may be wrong (with the system) would > be helpful. Things that can effect your particular case: Are you running a Sun VM on the second system? I see that you could still reproduce the problem with the JRocket VM on the first system. Are the graphics libraries exactly the same? gtk2? are you using the same version of the same window manager (like metacity) on both boxes? Are you running a desktop manager on one but not the other. Or have you changed things like the mouse policy (focus follows mouse, for example)? If SWT doesn't get shell activation events, that can lose active window instructions. I can't reproduce the problem here, but I'm on RHEL 5. PW
Hi. Thank you for taking a look. > Are you running a Sun VM on the second system? I see that you could still > reproduce the problem with the JRocket VM on the first system. Yes. > Are the graphics libraries exactly the same? gtk2? They are slightly different. "rpm -qa | grep ^gtk2" returns On the bad system gtk2-engines-2.18.4-5.el6.i686 gtk2-devel-docs-2.18.9-4.el6.i686 gtk2-immodule-xim-2.18.9-4.el6.i686 <= only here gtk2-2.18.9-4.el6.i686 gtk2-devel-2.18.9-4.el6.i686 On the good system gtk2-2.18.6-2.el6.i686 <= only here gtk2-devel-docs-2.18.9-4.el6.i686 gtk2-engines-2.18.4-5.el6.i686 gtk2-2.18.9-4.el6.i686 gtk2-devel-2.18.9-4.el6.i686 > are you using the same version of the same window manager (like metacity) on both boxes? Are you unning a desktop manager on one but not the other. BIG difference here. On the good system, GNOME is run. I access the system using VNC viewer. I then do Applications->Accessories->Terminal to open a terminal window and start the eclipse from the command line. It also runs Nautilus 2.30.0. On the bad system, no manager seems to be run. I access the system using VNC viewer the, and the VNC window shows a single terminal window. I start the eclipse from the command line there. > Or have you changed things > like the mouse policy (focus follows mouse, for example)? No

I start the > eclipse from the command line there. OK, this is the difference that matters. The window manager plays a big roll in providing shell activation events/focus events. SWT needs a window manager to be present. Without that, we won't correctly activate/deactivate the WorkbenchWindow. Even when we run our headless tests against Xvnc or Xvfb, we must start a window manager like: Xvfb :8 -screen 0 1280x1024x24 -auth auth.cfg & DISPLAY=:8.0 metacity --display=:8.0 --replace --sm-disable >/dev/null 2>&1 & You need to start a window manager of some kind on that system (even twm should provide some more stability). You can post back to this bug if this helps/doesn't help you. PW
Hi. Thank you very much for help! I changed my .vnc/xstartup to start gnome, and now run eclipse from it. And the error seems to have gone away (well at least for now. :-))
