    Description

      If a jar that does not contain directory entries (perhaps it was created with zip -D or --no-dir-entries) is reinitialized by VFS and an attempt is made to access a directory, an exception is thrown:

      java.lang.RuntimeException: Failed to initialize ZipWrapper: /apps/barc-middleware/applications/jboss-as/servers/swebitpd-websupp/deployers/jbossws.deployer/spring-core.jar/META-INF/
