A DESCRIPTION OF THE REGRESSION :
The Carousel Components Demo Application fails to load using Mustang-b72 webstart. It loads and runs fine using 5.0u6 webstart. It 's a regression in Mustang.
 
The JNLP references a php file, while the href in the JNLP file references a jnlp file:

http://www.xoetrope.com/zone/articles/files/carouselcomponents/webstart/CarouselComponents_ip.php
http://www.xoetrope.com/zone/articles/files/carouselcomponents/webstart/CarouselComponents_ip.jnlp

Etheral traces confirm that the php version is loaded, and then the jnlp version is attempted in both tiger (5.0) and mustang (6.0)  The difference is that tiger continues to load and mustang reports an exception that it cannot find the 404 file.

Note that the offile-allowed element IS present.


REPRODUCIBLE TESTCASE OR STEPS TO REPRODUCE:
Use the command line to access the jnlp file

<path to JDK>\bin\javaws.exe http://www.xoetrope.com/zone/articles/files/carouselcomponents/webstart/CarouselComponents_ip.php



RELEASE LAST WORKED:
5.0 Update 6

RELEASE TEST FAILS:
mustang-b70/b72

Tested on win 2000 pro(sp4)/solaris-sparc9 (gnome2)

EXPECTED VERSUS ACTUAL BEHAVIOR :

EXPECTED:
The demo application should load and run.  This is because the offline-allowed element is present in /jnlp/information

ACTUAL:
Java Webstart throws "Unable to lauch the application" exception and the demo fails to load.
