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This is may be somewhat outdated info but the situation about two months 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.

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