        * java/net/URL.java (getFile): Clarify return value doc.
        (getPath): Return null if file is empty - not empty String.
        (set): Convert protocol to lower case before doing anything.
        Only change the protocol handler if it's different.

        * java/net/URL.java (URL): Convert protocol to lower case before
        doing anything, so we getURLStreamHandler() with the proper value.
