> According to the specification of {{net.jini.url.httpmd.Handler}} the message digest may contain the '{{,}}' (comma) character, however the parsing logic in {{net.jini.url.httpmd.Handler.sameFile(URL, URL)}} assumes the first comma in the parameter part to be the start of the comment. As a consequence the following piece of code (requires the installation of a security provider with support for the non existing message digest algorithms {{MD5,0}} and {{MD5,10}}) yields the wrong result:
> {noformat:nopanel}
> URL url1 = new URL("httpmd://localhost:80/;md5,0=7be207c7111e459eeea1c9b3d04f1667,.jar");
> URL url2 = new URL("HTTPMD://localhost/;md5,10=7be207c7111e459eeea1c9b3d04f1667");
> System.out.println("equals: " + url1.equals(url2));
> {noformat}
> The output is "{{true}}" while it is of course obvious that the output should be "{{false}}" here.
