How WebSphere and WebLogic deal with stuck and hung threads

To understand how WebLogic deals with stuck threads read http://adfhowto.blogspot.com/2011/11/dealing-with-weblogic-stuck-threads.html 

WebSphere Application Server has similar capabilities to detect hung threads; however; WebLogic goes one step further for remediation . It restarts the server when all threads are stuck or a certain # of threads beyond a threshold are stuck.

Starting WebSphere Application Server 8.5, the new Intelligent health management feature supports restarting a server that has a certain configurable threshold of stuck threads.   That is, you can configure a health policy which says "when the number of hung threads exceeds some threshold, then perform some actions", and one of those actions is to restart the server. We are better than WebLogic because WAS restarts the server in a smart way in order to avoid an outage; that is, we know how many cluster members are running.
