[JBoss] No ManagedConnections available / JCA max connection (session)
----------------------------------------------------------------------

                 Key: JCR-2520
                 URL: https://issues.apache.org/jira/browse/JCR-2520
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-jca
    Affects Versions: 2.0.0
         Environment: JBoss 4.2.3.GA, PostgreSQL 8.x
            Reporter: Cédric Chantepie


It seems that with Jackrabbit JCA 2.0.0 deployed on JBoss 4.2.3.GA, "only" 20 session can
be opened at the same time.
When trying to open the 21th session, I get the following exception :

15:49:16,047 ERROR [STDERR] Caused by: javax.resource.ResourceException: No ManagedConnections
available within configured blocking timeout ( 30000 [ms] )

15:49:16,047 ERROR [STDERR]     ... 28 more

I don't see this limit / max count in Jackrabbit JCA configuration. I've checked whether it
comes from underlying PersistenceManager.
Persistence manager is postgresql bundle one from JNDI (with javax.naming.InitialContext as
driver).
But JBoss JMX console displayed it still have available connection to used database whereas
Jackrabbit JCA keep throwing exception.
Moreover I'm still able to use underlying datasource to get a JDBC connection and execute
a PreparedStatement ("SELECT * FROM default_bundle" as test).

So as I think underlying datasource/persistence manager is ok, there may be a trouble with
Jackrabbit JCA.
