JSR on Continuations

It has been a bit quiet around native continuations in java for a while. I think especially the post from Glad Bracha killed some momentum. But Geert Bevin has just lately revived the discussion on the codehaus list a bit. He picked up on the plan to formulate a JSR for continuations in java.

A few months ago Avi summarized some of the most prominent opinions on continuations. To me it sounds like there is a lot of mixing up of concerns. For example you don’t necessarily need sessions for continuations. (You could serialize the state into the page just like you would with basic POSTs) Using sessions or not is really a different decision. And continuations are not necessarily tight to the web. Mobile agents and workflow systems are well known use cases. So give his summary a read. IMO he raises some valid points.
