java.net.URL.equals requires SocketPermission (host resolve) in jdk1.2fcs.
This is not documented and causes JCK test failures in restricted environment
(appletviewer).

Here is a minimized test demonstrating the problem:
====== URLTest.java ========
import java.net.URL;

public class URLTest extends java.applet.Applet {

    public void init() {
        try {
            URL url1=new URL("http://some.host/index.html");
            URL url2=new URL("http://some.host/index.html");
            System.out.println(url1.equals(url2));
            System.out.println("OKAY");
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }

}
====== URLTest.html ========
<applet
    code="URLTest.class"
    width=600 height=400
>
[[You need a Java-aware browser to see the JavaTest Slave applet.]]
</applet>
====== Sample run (jdk1.1.7, jdk1.2beta4) =========
% appletviewer URLTest.html
true
OKAY
^C
====== Sample run (jdk1.2fcsL - REGRESSION) =========
% appletviewer URLTest.html

===========

==== Here is the spec for URL.equals ====
    /**
     * Compares two URLs. The result is <code>true</code> if and
     * only if the argument is not <code>null</code> and is a
     * <code>URL</code> object that represents the same
     * <code>URL</code> as this object. Two URL objects are equal if
     * they have the same protocol and reference the same host, the
     * same port number on the host, and the same file and anchor on
     * the host.
     *
     * @param obj the URL to compare against.
     * @return <code>true</code> if the objects are the same;
     * <code>false</code> otherwise.
     */
    public boolean equals(Object obj)

Note: the two URLs in the example are exactly equal according to the spec
so true should be returned.
