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

HttpURLConnection, d) setting some header fields and actually invoking
connect() on it, and then, with zero exceptions having been thrown thus
far:

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.

Does anyone have a useful response to this?

I construct an http URL -- no exception is thrown -- and open a
connection. Attempting to get the response code throws
MalformedURLException. This shouldn't be happening, as near as I can
tell.

Please give us a short example that recreates the problem. Otherwise we
are operating blindly.
