I stumbled over the following thread in the hibernate forum about JCS problems:
http://forum.hibernate.org/viewtopic.php?t=924937
thought it might be useful to know before going JCS. there's also an alternative (EHCache) mentioned.
I've been using EHCache in production with Hibernate, and have no problems to report about it, even though the load is very light.
EHCache's license, unlike Hibernate's, is APL 1.1, by the way.
