Resynced with GNU Classpath: fixes for file:// connections to directories

2005-03-02  Dalibor Topic  <robilad at kaffe.org>

        Resynced with GNU Classpath.

        2005-02-27  Chris Burdess  <dog at gnu.org>

        * gnu/java/net/protocol/file/Connection.java: Return correct content
        length for directory listing.
        * java/net/URLClassLoader.java: Correction for URLClassLoader, bug
        #11285: return valid URLs for directories.
