SISM blocks the item state cache when loading a new item
--------------------------------------------------------

                 Key: JCR-2546
                 URL: https://issues.apache.org/jira/browse/JCR-2546
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
          Components: jackrabbit-core
            Reporter: Jukka Zitting


The SharedItemStateManager.getNonVirtualItemState() method contains a loadItemState() call
within a "synchronized (cache)" block. This prevents all item state cache access while a new
item is being loaded from the persistence manager. I have at least one case where this has
caused a serious performance drop, essentially synchronizing repository access for all readers.
