Weld SE container does not properly load extension classes at boot
------------------------------------------------------------------
Key: ARQ-335
URL: https://jira.jboss.org/browse/ARQ-335
Project: Arquillian
Issue Type: Bug
Components: Weld Containers
Affects Versions: 1.0.0.Alpha4
Environment: Weld 1.1.0.Beta1
Reporter: Lincoln Baxter III
ServiceLoader needs to be used to load the extensions and add then to the Deployment:
