Subject [jira] Created: (JCR-20) Logging into a repository with a big version history takes a long time

Logging into a repository with a big version history takes a long time
----------------------------------------------------------------------

         Key: JCR-20
         URL: http://nagoya.apache.org/jira/browse/JCR-20
     Project: Jackrabbit
        Type: Bug
 Environment: Jackrabbit SVN 76106
    Reporter: Felix Meschberger
    Priority: Critical


Wenn a SessionImpl instance is created, the VersionManager.getVirtualItemStateProvider method
is called. This method - amongst other things - loads the complete (!) version history into
memory and walks through it to do some mapping.

Besides taking a long time (near 1 minute just to get the version history through PersistentVersionManager.getVersionHistories())
mapping the version histories ultimately results in an "OutOfMemoryError".

Currently there are 768 version histories and this is only a very small fraction of the expected
final number of version histories in my application
