Subject [jira] Commented: (JCR-1715) Prevent excessive Path.Element instances
Date Fri, 08 Aug 2008 14:57:44 GMT

    [ https://issues.apache.org/jira/browse/JCR-1715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12620945#action_12620945

Marcel Reutegger commented on JCR-1715:

A note on the Path.Element cache in PathFactoryImpl. Because equals and hashCode on Path.Element
is defined to use the normalized index I had to limit the cacheable path elements to the ones
with an undefined index.

>                 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
>         Attachments: JCR-1715-part1.patch, JCR-1715-part2.patch
> 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).
