Build Identifier: During work on a GWT project, repeatable PermGenSpace error dialogs occur causing eclipse to hang for a while and then exit immediately. After a restart the same problem occurs after a few minutes. Error often occurs in association with auto completion being used or when trying to refactor code. !ENTRY org.eclipse.osgi 4 0 2011-05-21 20:10:31.187 !MESSAGE Shutdown error !SESSION 2011-05-21 20:10:43.937 ----------------------------------------------- eclipse.buildId=I20100608-0911 java.version=1.7.0-ea java.vendor=Sun Microsystems Inc.

I have increased the PermGen in the eclipse ini-File (up to 512MB) but the error still occurrs.
Do your coworkers hit this problem too? Do you get the problem when not working with GWT? Do you get the problem if you use Eclipse with a Java 6 runtime?
Moving to Platform/Runtime
(In reply to comment #2) > Do your coworkers hit this problem too? Do you get the problem when not working > with GWT? Do you get the problem if you use Eclipse with a Java 6 runtime? This is a private project therefore there are no coworkers. I get the problem as soon as there is an open gwt project in eclipse. If my workspace has no gwt projects, then everything works fine. I already use Java 6 runtime.
(In reply to comment #4) > I get the problem > as soon as there is an open gwt project in eclipse. So once you create one GWT project the error appears? (In reply to comment #4) > I already use Java 6 runtime. (In reply to comment #0) > java.version=1.7.0-ea > java.vendor=Sun Microsystems Inc. That's not what your JRE seems to think it is.

Oops, i have confused with the project settings JDK. I have deinstalled jre 7, now using 6 with eclipse. same error box occurred after a while, but this time as i click it away i am at least able to continue to work. will continue to keep an eye on it.

The crash occurred again.
Does the error always occur in that SaveManager.saveMasterTable code, or is that just a random example? Is this the GWT SDK you are running?
(In reply to comment #8) > Does the error always occur in that SaveManager.saveMasterTable code, or is > that just a random example? > > Is this the GWT SDK you are running? Yes, it is the GWD SDK (v2.2.0). The error occurs on different code passages. Here is another sample stacktrace: !ENTRY org.eclipse.ui 4 0 2011-05-23 20:52:19.671 !MESSAGE Unhandled event loop exception !STACK 0 org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.OutOfMemoryError: PermGen space) at org.eclipse.swt.SWT.error(SWT.java:4083) at org.eclipse.swt.SWT.error(SWT.java:3998) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:137) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4041) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3660) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2629) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2593) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2427) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:670) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:663) 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(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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) Caused by: java.lang.OutOfMemoryError: PermGen space
Can you paste the contents of your eclipse.ini file here?
Here are the contents of my eclipse.ini. i have only edited the line with the permsize settings according to http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F -startup plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503 -showsplash org.eclipse.platform --launcher.defaultAction openFile -vmargs -XX:PermSize=256M -XX:MaxPermSize=256M -Xms128m -Xmx1024m
(In reply to comment #11) > -vmargs -XX:PermSize=256M -XX:MaxPermSize=256M Every option must be on its own line.
(In reply to comment #12) > (In reply to comment #11) > > -vmargs -XX:PermSize=256M -XX:MaxPermSize=256M > > Every option must be on its own line. Yes, this is the problem. You are running with default perm gen settings because only one property per line is read.
