open source project with thread / concurrency ?

[Edward Chen]

I want to improve my knowledge in thread / concurrency. For myself, the best way to achieve this is to study an open source. I have studied the Struts, Roller, Liferay, I learn a lot.

Now on thread, do you have recommendation of an open source project which has perfectly designed and implemented the java thread technology ? and this project is in production.

Thanks.
