    [ https://issues.apache.org/jira/browse/GERONIMO-5741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12974112#action_12974112

Shenghao Fang commented on GERONIMO-5741:
-----------------------------------------

Initial Analysis:

Code segments of org.apache.geronimo.connector.wrapper.outbound.JCAConnectionFactoryImpl

46    private final GenericConnectionManagerGBean connectionManager;
...
62    @Override
63    public JCAManagedConnectionFactory getManagedConnectionFactoryInstance() {
64        return ((JCAManagedConnectionFactory)connectionManager.getManagedConnectionFactory());
65    }

At line 64, the type of connectionManager is GenericConnectionManagerGBean, and GenericConnectionManagerGBean
is inherited from AbstractConnectionManager.
So the actual called method is AbstractConnectionManger.getManagedConnectionFactory().

Code segments of org.apache.geronimo.connector.outbound.AbstractConnectionManager

61    public ManagedConnectionFactory getManagedConnectionFactory() {
62        return managedConnectionFactory;
63    }

AbstractConnectionManger.getManagedConnectionFactory() returns an instance of type ManagedConnectionFactory
which does not implement the Interface JCAManagedConnectionFactory.
