Sorry for joining this discussion so late, I am forced to read the maillist on gmane lateley due to mail problems at our office :-(
This is may be somewhat outdated info but the situation about two months ago was as following. There were a number of open bugs reported with JCS and several users had expressed frustration that their patches and contributions had been ignored. I think it was part of the reason at least two independent forks had been started.
One of these, EHCache is what Hibernate has been shipping successfully for a few months now. It's a *very* lightweight package compared to JCS and only provides a memory cache with disk overflow capabilities. It's licensed with an Apache 1.0 license. The issues concerning copyright owner I reported earlier have been solved. I've been using it in at least three production sites for a few months now without having any problems.
The advantage of JCS is that it boasts a lot more functionality (distributed, pluggable, etc) and of course that it is an apache project. I think a lot of issues may have been solved since I last looked because there was a surge of activity on the maillinglist some time ago and some new committers were proposed then. But I haven't personally used or tested it myself and I've not been monitoring progress since.
I think we can use either EHCache or JCS as our default cache solution. Both have their own merits. I personally tend a bit towards EHCache because I know it works well.One thing to note however is that EHCache does not persist its disk overflow beyond shutdown by design. JCS does, but that feature didn't work.

seems to prefer JCS store
Can someone summarize the pro and cons of both JCS and EHCache, both from a license and technical POV?
