As the Subject: says. I'm getting the odd MalformedURLException after

int rc = uc.getResponseCode();

throws.

It must be constructing new URLs under the hood. And making mistakes
sometimes.

Looks like Sun's bug, not mine, unless there's something else users of
java.net should be checking for that I'm not besides the obvious.

It's another strange one.

Since you keep running into trouble, I would suggest you use a java 1.5
instead of 1.6. If you still have trouble, think about what YOU could
do differently. This is the third post of yours where the "library" has
a bug. With something as widely used as Java, this is highly unlikely.

If you're problem persists in Java 1.5, then it is probably *your* bug.
If it goes away, then it should be reported in Sun's bug database.

Try to create an sscce http://www.physci.org/codes/sscce/ that
recreates the problem. If you can post that here (or for any of your
other threads), we might be able to help you understand why it isn't
working. Otherwise a blind stacktrace (even with some context) isn't
going to help us help you.

Good luck,
Daniel.
