With a temporary workaround to the beanManager issue (simply replaced "entry.getKey().getId().equals("flat"))" by "entry.getKey().getClass().getName().contains("org.jboss.weld.integration.")") I ran into an issue involving the service registry. I'm not sure if this is related to the beanManager issue or not, but the problem is that Weld complains if a new BDA created by Deployment.loadBDA method has a clean service registry:


DEPLOYMENTS IN ERROR:
  Deployment "vfs:///home/fla/Development/projects/jbossas-trunk/testsuite/output/lib/weld-translator.ear_WeldBootstrapBean" is in error due to the following reason(s):
org.jboss.weld.exceptions.ForbiddenStateException: WELD-000117 Required service org.jboss.weld.injection.spi.EjbInjectionServices has not been specified, **ERROR**

    at org.jboss.deployers.plugins.deployers.DeployersImpl.checkComplete(DeployersImpl.java:1370) [:2.2.0.Alpha6]
    at org.jboss.deployers.plugins.deployers.DeployersImpl.checkComplete(DeployersImpl.java:1316) [:2.2.0.Alpha6]



So, I created a workaround to populate the loaded BDA service registry, just to see if the error would go away. DeploymentImpl initializes the loaded BDA service registry with a copy of the service registries of the BDAs contained in the DeploymentImpl (only services added during bootstrap).

This makes WeldNumberguessExampleUnitTestCase to pass, but WeldTranslatorExampleUnitTestCase still fails, stating that TranslatorControllerBean is ambigously defined:

DEPLOYMENTS IN ERROR:

    at org.jboss.profileservice.management.AbstractActionController.internalPerfom(AbstractActionController.java:234) [:0.1.0.Alpha1]


So, the problem is that Weld finds two EjbDescriptors of the same bean. One in the BDA that represents weld-translator.ear, included in the corresponding DeploymentImpl, and another one in the bda that has been loaded by the Deployment, representing resteasy.deployer.

If I still initialize the loaded BDA service registry with a copy of the other BDAs service registry, but this time adding a new, clean, JBossEJBServices to the loaded BDA serviceRegistry, and putting no EjbInjectionServices in it, I get a message complaining that the injection point has unsatisfied dependencies:


DEPLOYMENTS IN ERROR:

If anybody wants to retrace my steps, there is a  https://jira.jboss.org/browse/JBAS-8250 patch attached to Jira that can be applied to JBoss AS trunk. You can check loadBDA implementation  http://anonsvn.jboss.org/repos/jbossas/trunk/weld-int/deployer/src/main/java/org/jboss/weld/integration/deployer/env/bda/DeploymentImpl.java here.

So, what is expected from the ServiceRegistry of a newly created BDA? Should it be initialized with some services? Which ones?
