I've managed to create a testcase in jboss trunk that reproduces this problem. It's a hack, so I haven't ported it to JBoss5. While looking at the problem I also found: https://jira.jboss.org/jira/browse/JBVFS-89 I don't know whether that it is the cause. The syptom is jar files that have isLeaf() == true and it only occurs if the spaces in the VFSContext part of the original path.
