Eclipse hang saving workspace - workbench state on exit
Happens frequently on my windows 7. Have to kill E using Task manager.
Please provide exact version of your Eclipse. Please create thread dump with jstack at the time Eclipse hangs and attach it here.

Version: Mars.2 Release (4.5.2) Build id: 20160218-0600
Looks like Mylyn does some weird things and hangs in ExternalizationManager, see "ModalContext" #1299 prio=6 os_prio=0 tid=0x000000002008d000 nid=0x33c8 in Object.wait() [0x000000001d5ee000] java.lang.Thread.State: TIMED_WAITING (on object monitor) at java.lang.Object.wait(Native Method) at org.eclipse.core.internal.jobs.Semaphore.acquire(Semaphore.java:39) - locked <0x00000000edee7ff0> (a org.eclipse.core.internal.jobs.Semaphore) at org.eclipse.core.internal.jobs.JobManager.join(JobManager.java:909) at org.eclipse.core.internal.jobs.InternalJob.join(InternalJob.java:341) at org.eclipse.core.runtime.jobs.Job.join(Job.java:458) at org.eclipse.mylyn.internal.tasks.core.externalization.ExternalizationManager.saveNow(ExternalizationManager.java:162) at org.eclipse.mylyn.internal.tasks.core.externalization.ExternalizationManager.stop(ExternalizationManager.java:143) at org.eclipse.mylyn.internal.tasks.ui.TasksUiPlugin$5.saving(TasksUiPlugin.java:604) at org.eclipse.core.internal.resources.SaveManager.executeLifecycle(SaveManager.java:387) at org.eclipse.core.internal.resources.SaveManager$1.run(SaveManager.java:196) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.resources.SaveManager.broadcastLifecycle(SaveManager.java:199) at org.eclipse.core.internal.resources.SaveManager.save(SaveManager.java:1184) at org.eclipse.core.internal.resources.Workspace.save(Workspace.java:2270) at org.eclipse.ui.internal.ide.application.IDEWorkbenchAdvisor$4.run(IDEWorkbenchAdvisor.java:453) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:119)
This is reminiscent of bug 392794 but seems to be different. But it looks like it could be a bug in the jobs framework again - this code should not hang unless the saveJob is running, but it is not in the thread dump: bc. saveJob.schedule(); saveJob.wakeUp(); saveJob.join();

I experienced the same issue today for the first time. I run Eclipse neon.3. I see two threads waiting at org.eclipse.core.runtime.jobs.Job.join(Job.java:524) "ModalContext" and "Worker-282"

Comment on attachment 268572 [details] Jstack dump of Eclipse shutdown hung saving workbench state 1st time posting - hope this is correct and useful, SORRY!
I've experienced this many times before, ussualy every day! I currently haver Neon.3 but I experenced the problem with older releases as well. Hints: I normally have Eclipse open the whole day (even overnight) and have 3-5 huge Java projects in my worskspace. Just now it happened that I was debugging, left the computer for 2 hours. Then cam back and Open Type nor Open Resource stopped working (type something but nothing found). Stopping the application from the Debug view (stop button) didn't stop the project. Thease are the typical symptoms. That's when I needed to restart Eclise. And then the Save Workspace dialog appers and stops in about 1/3 and hangs indefinitely. So I kill Eclipse and strart it again. What's totally annonying that hitting Ctrl+B (build all) starts Clean & build of the last project, which takes some time!

Created attachment 273565 [details] Eclipse STS 3.9.1 / Eclipse 4.7.1a saving workspace freeze I observe the same behaviour as in comment #14. It seems to be related to the amount of memory that Eclipse JVM consumes, because I don't observe problem when closing Eclipse after short period of working in it (e.g. one day).

I'm experiencing this problem as well. Is this on anybody's radar to get fixed?
