Description Mik Kersten CLA 2008-01-15 20:09:31 EST 
From bug 188524 comment#60:

It started to appear again after updating to 2.2 release:

While loading class "org.eclipse.mylyn.internal.tasks.ui.WorkspaceAwareContextStore", thread "Thread[main,6,main]" timed out waiting (5000ms) for thread "Thread[Worker-4,5,main]" to finish starting bundle "update@plugins/org.eclipse.mylyn.tasks.ui_2.2.0.I20071220-1700.jar [275]". To avoid deadlock, thread "Thread[main,6,main]" is proceeding but "org.eclipse.mylyn.internal.tasks.ui.WorkspaceAwareContextStore" may not be fully initialized.

org.osgi.framework.BundleException: State change in progress for bundle "update@plugins/org.eclipse.mylyn.tasks.ui_2.2.0.I20071220-1700.jar" by thread "Worker-4".

Comment 1 Willian Mitsuda CLA 2008-01-21 15:47:38 EST 
Note: this happens in every startup.
Comment 2 Willian Mitsuda CLA 2008-01-21 23:19:31 EST 
I just updated to I20080121-1430 and it appears to have stopped. But I'll keep an eye on this.
Comment 3 Steffen Pingel CLA 2008-02-12 22:22:18 EST 
I think what might have triggered these warnings is the following: Tasks UI was updated but Context UI was not. This was possible due to a missing feature dependency. The old bundle activation of Context UI tried loading ITaskHighlighter from Tasks UI which triggered the deadlock. A subsequent update of Mylyn updated Context UI which is why these warnings don't appear anymore.
Comment 4 Mik Kersten CLA 2008-02-13 20:39:18 EST 
Willian: Steffen and I investigated this and it should no longer be possible with the Mylyn 2.2 fixes.  We have made additional improvements since as well, but our current theory is that your plug-ins were partially updated due to ..mylyn.context.ui not specifying the correct dependency.  If you see this again please reopen.
Comment 5 Willian Mitsuda CLA 2008-02-13 21:52:21 EST 
OK! I didn't see this anymore too.
Comment 6 Helen Bershadskaya CLA 2008-03-13 12:28:03 EDT 
I am still seeing this problem with Mylyn 2.3 on top of Eclipse 3.3.3.  It happens very regularly for me.  There are quite a few other plugins we are loading on top of the base Eclipse platform, so I am not sure if that makes a difference also.

Below is the whole workspace log file section from the beginning up to and including the mylyn stack trace.

Comment 10 Steffen Pingel CLA 2008-04-24 21:15:40 EDT 
This is caused by the early startup of the UiUsageMonitorPlugin. Mik, reassigning to you.
Comment 11 Mik Kersten CLA 2008-05-15 03:08:17 EDT 
Steffen: I broke this cycle by making UiUsageMonitorPlugin.getMonitorLogFile() not depend on ContextCore.  I fixed the warning messages in the log by making addMonitorPreferences(..) instantiate the monitor lazily.  Please review the two landmarks in the task context.
