FYI, I have just tagged 3.0.1.GA which contains some bug fixes and a performance tweak pertaining to passivation.

    * [ JBCACHE-1444 ] ObjectName's validation fails for Jbosscache 3.0 on WAS 6.1 due to ":" char in name.
    * [ JBCACHE-1445 ] Data gravitation cleanup does not happen when using single-phase commits.
    * [ JBCACHE-1448 ] Jdbm and BDBJE cache loader incorrectly reading database name from location String
    * [ JBCACHE-1446 ] Optimize activations by minimizing calls to cacheloader.exists()

This should be released shortly.
