> Configure the use of the OracleDatabasePersistencePlugin for EJBTimers:
>    <!-- A persistence policy that persistes timers to a database -->
>    <mbean code="org.jboss.ejb.txtimer.DatabasePersistencePolicy" name="jboss.ejb:service=EJBTimerService,persistencePolicy=database">
>      <!-- DataSource JNDI name -->
>      <depends optional-attribute-name="DataSource">jboss.jca:service=DataSourceBinding,name=DefaultDS</depends>
>      <!-- The plugin that handles database persistence -->
>      <attribute name="DatabasePersistencePlugin">org.jboss.ejb.txtimer.OracleDatabasePersistencePlugin</attribute>
>    </mbean>
> Error:
> --------
> The org.jboss.ejb.txtimer.OracleDatabasePersistencePlugin extends GeneralPurposeDatabasePersistencePlugin and implements a method
>    public List selectTimers() throws SQLException;
> In order to override the behavior of the GeneralPurposeDatabasePersistencePlugin the correct signature must be 
>    public List selectTimers(ObjectName containerId) throws SQLException;
> Hence the following exception occurs when restoring persisted timers at server startup:
