[cp-patches] A bugfix for Inet6Address and URLClassLoader

[Ivan Maidanski]

Hi!

This patch does the following:
- fixes a bug in 2 methods of Inet6Address;
- fixes a bug (unquotes the paths) in URLClassLoader (same as in 
http://article.gmane.org/gmane.comp.java.classpath.patches/12985/);
- makes MalformedURLException message (in URL class) more end-user-friendly 
(e.g., if someone specifies "www.xyz.com" instead of "http://www.xyz.com"; (for 
new URL(url)) then the thrown message would be "No protocol specified: 
www.xyz.com" instead of "Absolute URL required with null context: www.xyz.com").

ChangeLog entries:
        * java/net/Inet6Address.java:
        (isLinkLocalAddress()): Fix a bug (cast integer const to byte).
        (isSiteLocalAddress()): Likewise.
        * java/net/URL.java:
        (URL(URL, String, URLStreamHandler, boolean)): Replace
        "Absolute URL required with null context" exception message with
        a more user-friendly "No protocol specified" (matches that in the RI).
        * java/net/URLClassLoader.java:
        (addURLImpl(URL)): Do "unquote" of the URL file path.
        (getPermissions(CodeSource)): Likewise.
        (getPermissions(CodeSource)): Replace '/' in the URL file path to
        a platform-dependent one.

Regards.
