Profiler Bugs related to caching:
Improve Profiler Hashmap Usage
Profiler Admin is not refreshed after seed xml import.
Resolved for 2.2.0. Randy has addressed memory usage by putting a session listener in place and pulling cache entries out on session expiration. While not a completely controlled solution as we have with ehcache, it does expire sessions and keep the size down. The impact of putting in a ehcache was too high at this point. See JS2-881 for that solution
Update Fix Version target to 2.1.1 as 2.1.1-RC is already tagged
