(JBossMetaData#705@67155) I looked at what the "mustOverride" param does in JBossEnterpriseBeansMetaData and it doesn't control what happens when beans are missing in the spec metadata. It just gets passed in to JBossEnterpriseBeanMetaData.merge for each bean that exists in the spec metadata. JIRA for this is http://jira.jboss.com/jira/browse/JBAS-5018 .
