Do you have evidence that JDT UI is burning the cycles? Can you please attach some thread dumps?

Comment 3 benjamin.herzig 2011-06-23 08:54:21 EDT

See http://wiki.eclipse.org/index.php/How_to_report_a_deadlock.

Thread dump of Eclipse when CPU 100% for more than 30min

run with kill -3 <pid>

Comment 7 Adam Pullen 2011-07-10 06:46:56 EDT

Hello, 

Also had this problem with the "net.sf.redmine_mylyn.ui". Was fixed by using the "development" version of the UPDATE site.
See: (http://sourceforge.net/tracker/index.php?func=detail&aid=3175794&group_id=228995&atid=1075435)

--HOWEVER--
I am still getting 100% CPU usage when Eclipse is just sitting there. Attached is the thread dump.

Is there anything else i.e. in eclipse can i see the "thread(s)" that are burning cycles?

It is sporadic and i have not managed to find a sequence to reproduce it.

If there is anything else that i can provide please just let me know

Comment 8 Dani Megert 2011-07-11 08:46:40 EDT

The event loop itself is idle and the running threads are from Android tooling.

Please report your bug there.

Comment 9 Shawn Lauzon 2011-07-19 20:13:58 EDT

Huh, I just ran into the same exact thing. Too bad the OP never posted a link to a bug in the Android tooling. Guess I'll have to search there.
