A DESCRIPTION OF THE PROBLEM :
Java Webstart does not work on Windows 7.

I am developing the project on http://raven.java.net. Recently I created a webstart distribution of it. While it runs fine on my Windows XP laptop, it does not run at all on my Windows 7 Ultimate desktop. Webstart will begin to download the jars and then freeze. No error is given. The download simply halts.

Apparently others are having this problem too:

 I presume Windows 7 is refusing to run webstart. I searched your bug database to see if anyone else reported this, but couldn't find any, so I'm starting a new bug.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use a computer running Windows 7 Ultimate. Go to a webpage with a webstart file on it, such as:

http://raven.java.net/apps/studio/RavenStudio.html
http://docs.oracle.com/javase/tutorial/uiswing/components/scrollpane.html

Click on the webstart link. The download will begin but not complete.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Webstart should run the executable program.
ACTUAL -
Download starts, but does not complete. No error message is given.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Apparently enabling Windows XP compatibility mode will fix this, but I've not tried it.
