bin/client/jboss-modules.jar contains invalid content of Implementation-Version in their META-INF/MANIFEST.MF. Although it contains "1.2.2.Final-redhat-1", file name itself doesn't include version at all. Additional info: see https://bugzilla.redhat.com/show_bug.cgi?id=927238
This issue reported against older version, cannot be reproduced against latest 6.3.0. bits, which means it was fixed earlier. Therefore, I'm closing this bug.
