#8 URLConnection not closed

[Anonymous]

The underlying HttpURLConnection is not disconnected if the ResourceTracker does not download a Resource (e.g. when the cached copy is up to date).
This means that the TCP connection to the HTTP server remains open until it times out on the server side. In an environment with a large number of clients and multiple resources per JNLP file this leads to performance issues on the server side.

I (christian.gawron@gmx.de) can provide a patch to ResourceTracker.java solving this problem.
