 * 3. from cdi get username and password<br>
 * 4. create ResourcePrincipal using default username and password<br>

 * 6. createManagedConnection using above subject<br>
 * 7. add a dummy ConnectionEventListener to the mc that simply handles connectionClosed
 * 8. getConnection from the ManagedConnection with above subject<br>
 *
 * @param poolInfo               The poolname from whose MCF to obtain the unpooled mc
 * @param principal                   The ResourcePrincipal to use for authenticating the request if not null.
 *                               If null, the pool's default authentication mechanism is used
