Summary: NullPointerException when calling DatabaseService.getAdapter

Initial Comment:
This exception is thrown when the OpenJMS server is
shutdown.  It doesn't happen always but when running
stress tests which include starting and stopping the
OpenJMS server frequently.

Here is the stack trace printed to the log file.  The
iweventsub is just a naming convention we use. 
Basically it is the OpenJMS server.

Is this a known issue?   I'm also appending the
database configuration in the config file.

 <DatabaseConfiguration>
    <RdbmsDatabaseConfiguration
        driver="oracle.jdbc.driver.OracleDriver"
        url="dbc:oracle:thin:@qatempl-sol:1521:chandra"
        user="scott"
        password="tiger"
        maxActive="10"
        maxIdle="5"
        minIdleTime="1800"
        evictionInterval="3600" />

  </DatabaseConfiguration>
