Description

I have a simple garbage collection task that runs periodically. After upgrading to 1.5.5 it started logging a warning shortly after each run:

2009-05-09 03:44:45,480 WARN [org.apache.jackrabbit.core.SessionImpl] - <Unclosed session detected. The session was opened here: >
java.lang.Exception: Stack Trace
at org.apache.jackrabbit.core.SessionImpl.<init>(SessionImpl.java:239)
at org.apache.jackrabbit.core.SystemSession.<init>(SystemSession.java:76)
at org.apache.jackrabbit.core.SystemSession.create(SystemSession.java:64)
at org.apache.jackrabbit.core.SessionImpl.createDataStoreGarbageCollector(SessionImpl.java:649)

So it's not my session, but an internally created SystemSession.

Code I'm using:
getTemplate().execute(new JcrCallback()
{
public Object doInJcr(Session session)
throws IOException, RepositoryException

{ SessionImpl sessionImpl = (SessionImpl)session; GarbageCollector gc = sessionImpl.createDataStoreGarbageCollector(); gc.scan(); gc.stopScan(); gc.deleteUnused(); return null; }

}, true);
