I heard you were collecting api changes for 1.0. I sent you this some time
ago and haven't heard back from you on it, so here a reminder about an api
change needed in java.net.URLStreamHandler to allow people to define their
own URL stream handler subclasses.

Thanks.

Sami,

It's me again, from DevPro-land with another suggested fix for you. Thanks
for including the last one I sent you in java.awt.

I needed to add a new URL protocol handler, and as luck would have it, the
new protocol is the first protocol under sun.net.www.protocol to attempt to
override the parseURL method provided by the superclass
java.net.URLStreamHandler.

I found myself unable to write a new parseURL method, however, because it
needs to use the protected set() method in the java.net.URL class. According
to a comment in the URL class, only new protocol handlers, derived from
URLStreamHandler, should be allowed to call the set() method on a URL. The
new protocol qualifies, but because it's in a different package it cannot
access protected methods in java.net.URL.

My solution is to provide a protected method in the URLStreamHandler class
that new handlers (derived from URLStreamHandler) can call to set a URL.

If you agree, please add the following method to the end of the
URLStreamHandler class in src/share/java/java/net/URLStreamHandler.java:

    /**
     * Calls the (protected) set method out of the URL given. Only
     * classes derived from URLStreamHandler are supposed to be able
     * to call the set() method on a URL.
     * @see URL#set
     */
    protected void setURL(URL u, String protocol, String host, int port,
String file, String ref) {
      u.set(protocol, host, port, file, ref);
    }


Thanks.
