QueryPlanCache grows without bound.   Eventually gets OutOfMemoryException
--------------------------------------------------------------------------

         Key: HHH-2431
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2431
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.2    
 Environment: all versions, all platforms
    Reporter: Eric Goff


Every time you execute a query, and that query does not match any existing queries
in the QueryPlanCache, that query is *always* added to the Query Plan Cache, along with
a lot of various antlr stuff.

There seems to be no way to control it.

Minimally, there should be some sort of heap of query plans where the
least used query plan is ejected when the cache reaches it max size.

The cache size should, of course, be user configurable.
