DB Connections established which fail check-valid-connection-sql do not immediatly close their connection
---------------------------------------------------------------------------------------------------------

                 Key: JBAS-5526
                 URL: http://jira.jboss.com/jira/browse/JBAS-5526
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: JBossAS-4.2.2.GA
         Environment: Red Hat Enterprise 5.1, MS SQL Server 2005
            Reporter: Dan Killey


When a DB connection is attempted to be created where it is configured with check-valid-connection-sql, if the socket/connection succeeds but the check-valid-connection-sql statement fails a connection remains open until GC. In a large volume environment this can lead to many sockets being opened until GC occurs and can thus run into file handle limits.

If a valid TCP connection was established, but the SQL fails, I am suggesting the connection should also be closed at the time of failure, not waiting till GC.
