Hi everyone

I have some questions about how the caching works in grouper 1.4.2 :
I have noticed, via visualvm, that a lot of instances of class net.sf.ehcache.Cache are created.
For instance, if I log in with GrouperSystem and I create a group there are 107 instances of Cache. Then I do the same operation with another user in another browser and there are 151 instances of Cache. And when I look in the debugger there is a lot of creation of CacheManager in the method initialize of the class
EhcacheContoller. Could you tell me if this is the expected behavior, with the caches associated to the sessions, or if I missed something ?
