Sure, but that doesn't mean that it would be reasonable to randomly
change the output of a given Class's toString() as long as it would be
easy for a person to read :)
I know that's not what you are advocating, and I certainly agree that no
one should depend on toString() output like that, but I also know that
in production systems *I* have done it, and I'm sure others have as well.

Well, we could actually print that if that was our impl of URLConnection
for HTTP, but still, I think
"org.apache.harmony.whatever.HttpURLConnection:http://www.apache.org";
would be more reasonable than
"Implementing Class : org.apache.harmony.whatever.HttpURLConnection,
Target URI : http://www.apache.org";
or something like that, even thought the second is perfectly good.
All I'm saying is that unless the output from the RI's toString() is
particularly brain-dead, it doesn't seem to be too much of a bother to
be similar.
