When symbolic links are used for server configuration directories, the vfs cached deployments are not found within the CombinedVFSCache permanent roots
-------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: JBVFS-137
                 URL: https://jira.jboss.org/jira/browse/JBVFS-137
             Project: JBoss VFS
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 2.1.3.SP1
            Reporter: Mike Clark
            Assignee: John Bailey


When a symbolic link (symlink) is used for a server configuration directory (for example, <jboss-home>/server/elsewhere -> /somewhere/default) there is a mismatch between paths used for the CombinedVFSCache's permanentroots and those used to find items in the cache.

"CombinedVFSCache" which is configured in <jboss-home>/server/<server-dir>/conf/bootstrap/vfs.xml.  In this configuration, several "permanentroots" are configured based on properties.  While the properites themselves utilize a path with the symlink, the URLEditor that converts the string to a URL will convert the path, resolving the symlink.  (This is because the URLEditor utilzes the org.jboss.util.Strings class which makes a call to java.io.File#getCanonicalFile())

However, lookups make into the cache will utilize a non-resolved path and thus do not match the permanent roots.  Due to another bug, JBVFS-134, this bug can lead to duplicate entries in the <jboss-home>/server/<server-dir>/tmp/vfs-nested.tmp directory and, ultimately,  to disk full errors.
