Subject [jira] Created: (JCR-1715) Prevent excessive Path.Element instances
Date Fri, 08 Aug 2008 14:25:44 GMT
Prevent excessive Path.Element instances

                 Key: JCR-1715
                 URL: https://issues.apache.org/jira/browse/JCR-1715
             Project: Jackrabbit
          Issue Type: Improvement
          Components: jackrabbit-core, jackrabbit-spi-commons
            Reporter: Marcel Reutegger
            Priority: Minor

Even when a CachingHierarchyManager is used jackrabbit creates a lot of Path.Element instances.
The internally used PathMap (spi-commons) creates new Path.Element instances whenever a path
is constructed, even when the path is constructed from cached PathMap.Elements.

Running a test with 10k nodes results in 250k Path.Element instances being created and held
in memory (mostly for events).
