An ear with no longer supported 'urn:jboss:bean-deployer:2.0' namespace in META-INF/jboss-beans.xml can be deployed to AS7 without any error. I tried to deploy it via command line copy and via web admin console. Both of them passed which is weird, because the same ear failed to deploy by Arquillian.
If I modified the namespace to 'urn:jboss:pojo:7.0' then deployment by Arquillian passed too.
It seems like META-INF/jboss-beans.xml is not fully processed if deployed by command line copy or by web admin console.
Note: it was tried with the latest master of AS7.
