A DESCRIPTION OF THE REGRESSION :
I have a signed applet which uses a URLConnection to retrieve content via HTTPS. Under the most recent Mustang beta, calling getContentType always returns null even though there is a MIME type set. This worked on 1.4.1_01 all the way to 5.0 Update 6.

-Wyatt

REPRODUCIBLE TESTCASE OR STEPS TO REPRODUCE:
In a SIGNED applet do the following:

URL url=new URL("http://www.sun.com/");
System.out.println(url.openConnection().getContentType());

You should see null in the console

RELEASE LAST WORKED:
5.0 Update 6

RELEASE TEST FAILS:
mustang-beta

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Calling getContentType should return the MIME type of the document being retrieved.
ACTUAL -
Calling getContentType always returns null
