Subject [jira] Created: (JCR-22) DefaultItemStateProvider contains grow-only cache
Date Tue, 23 Nov 2004 13:34:18 GMT
DefaultItemStateProvider contains grow-only cache
-------------------------------------------------

         Key: JCR-22
         URL: http://nagoya.apache.org/jira/browse/JCR-22
     Project: Jackrabbit
        Type: Bug
 Environment: Jackrabbit SVN 106295
    Reporter: Felix Meschberger


The DefaultItemStateProvider class contains a private HashMap "items" which contains references
to ItemState objects. The bad thing about this cache is, that it only grows, but is not being
managed to forget about "unused" items.

Example: A repository which is filled with 9350 nodes and 52813 properties grows this items
map to 1'667'557 (!) entries. In this concrete case, the VM all13ates 213MB to the heap of
which 57MB is referenced by the DefaultItemStateProvider.items map.
