2.2.0.CR7 is now available which does have JBCACHE-1383.  You should see your heap size drop.

While you may not have the time to play with this, I would advise to at least keep it on your radar.  It is _significantly_ faster than 2.X, and has a smaller memory footprint as well.  I expect to release Alpha2 this evening/tomorrow morning, and my goal is to have this in GA by the end of September.
