* Deployer responsible for "starting" a {@link Ejb3Deployment}.
*
* <p>
* The {@link Ejb3Deployer} creates and attaches a {@link Ejb3Deployment} into
* the deployment unit. The attached {@link Ejb3Deployment} will have it {@link Ejb3Deployment#create()}
* invocation completed by the {@link Ejb3Deployer}. This {@link Ejb3DeploymentDeployer} is just responsible
* for invoking {@link Ejb3Deployer#start()} *after* the deployment unit has been processed by the deployers
* which are responsible for attaching {@link Barrier SwitchBoard barrier} and {@link InjectionManager InjectionManager}
* to the unit.
* </p>
*
* <p>
* Note: This deployer ideally shouldn't have been required and the other {@link Ejb3Deployer} should have been
* sufficient for starting the {@link Ejb3Deployment}. But as soon as the {@link Barrier} is added a an input to the
* {@link Ejb3Deployer}, things start falling apart due to the weird circular dependencies that get introduced between the deployers,
* due to the various JBoss WS deployers.
