With the introduction of JBossMessageDrivenBean31MetaData in JBMETA-287, some of the tests fail with:

is in error due to the following reason(s): java.lang.ClassCastException: org.jboss.metadata.ejb.jboss.JBoss50MessageDrivenBeanMetaData cannot be cast to org.jboss.metadata.ejb.jboss.JBossMessageDrivenBean31MetaData

This needs to be fixed similar to what we did for JBossSessionBean31MetaData.
