After the fix to http://jira.jboss.com/jira/browse/JBAS-4355, the JBoss trunk now creates a MANIFEST only jbossall-client.jar with references to other jar files. The readme in that jar mentions this: anonymous wrote : | This jar file contains a classpath reference to various client jar files used by jboss client applications. | Each of the jar files in the following list must available in the same directory as the jbossall-client.jar, Otherwise they will not be found by the classloader. Now going forward, starting JBoss-5.0 CR1, does this jar serve any purpose to the client applications? Since anyways they will have to package the other jar files in their classpath.
