Ok, the second reason is convincing
Thanks,

2006/9/14, Andrew Zhang <[EMAIL PROTECTED]>:
There are two reasons:
1. Spec has explicitly pointed out "No validation of the inputs is performed
by this constructor."
2. The exception thrown sequence is really hard to follow, as described by
Ilya, see examples below:
1. new URL("ss", "0", -3, null);
java.net.MalformedURLException: Invalid port number :-3
2. new URL("ss", null, -3, null);
java.lang.NullPointerException
3. new URL("ss", "0", -3, "file");
java.net.MalformedURLException: Invalid port number :-3
4. new URL("ss", null, -3, "file");
java.net.MalformedURLException: unknown protocol: ss
5. new URL("ss", "0", -1, null);
java.lang.NullPointerException
Yes, we should follow RI for exception thrown sequence if possible. But for
thise case, would anyone suggest how to throw exception to follow RI?
