M9

After working some time in a M9 session I got to a point where I can't launch 
launch configurations, decorators doesn't update anymore and other things seem 
to hang.

The progress dialog that pops up after launching a launch/debug configuration 
showed that is is wating for an ongoing job. But the ongoing jobs window was 
empty.

The Progress view didn't show any jobs so I was wondering what was blocking. I 
figured out to enable verbose and closed & reopend the progress view which was 
now filled with all sleeping jobs.

After I've killed the _sleeping_ "Building workspace" jobs the launch 
configuration suddendly started fine.

dump while waiting

This is a thread dump while the launch job was waiting for "ongoing" jobs.

Gunnar, could you attach a screen shot of the progress view (in verbose mode) if
this happens again?

Screen shot

I've captured a case where it says "-1 work items left". Doesn't look good, but
the launch was successful afterwards.

Ignore the last screen shot. The format of the messages in the view is:

taskName - subTaskName

So the "-" does not mean "-1", it means "1" task left.

Don't ignore the screenshot, it's exactly the case that indicates when the 
build job is blocking things. I had to cancel the sleeping build job and then 
the launch started successfully. But the sleeping build job also blocked other 
things. I also noticed that there isn't any auto-build anymore at this stage. 
After closing and reopening Eclipse everything works again.

Screenshot of Progress view showing all jobs sleeping

Here is a screenshot of the Progress view in verbose mode. 

The screenshot shows all jobs sleeping. No build is happening although
auto-build is turned on and I saved some java classes several times.

I noticed a problem while switching the Progress view into the verbose mode. It
didn't show system jobs. I had to close it in all perspectives first and reopen
it to see all jobs. It seems that the progress view got stale.

This appears slightly different, but I believe this is a dupliate of bug 57565.
There was a bug that could cause a job to sleep forever.
