> The ClientFinalizer shutdown hook is not used.
> This can lead to severe memory leaks if you use the DFSClient in a dynamic class loading
context (such as in a webapp) as the DFSClient.ClientFinalizer class is retained in the memory
by the shutdown hook. It retains also the current ClassLoader and thus all classes loaded
by the ClassLoader. (Threads put in the shutdown hook are never garbage collected).
