Redeployment doesn't work with E-EJB3

I'm executing the following sequence:

EJB3StandaloneBootstrap.boot(null);
EJB3StandaloneBootstrap.deployXmlResource("META-INF/jboss-beans.xml");
EJB3StandaloneDeployer deployer = EJB3StandaloneBootstrap.createDeployer();
deployer.getArchivesByResource().add("META-INF/persistence.xml");

deployer.create();
deployer.start();

deployer.stop();
deployer.destroy();

deployer.create();
deployer.start();

This fails on the second start() with this:
