Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)

This is what happens:

If you have Firefox set as your default browser in Windows Vista and you have UAC turned ON and you are launching a java-application that is placed in the USERDIR/AppData/LocalLow directory by default and that java application is wrapped into an .exe application (using a wrapper like launch4j or jSmooth) and you want to open an URL from inside the application you have to use 


This works on all browsers (IE, Safari, Chrome, Opera) except Firefox because FF throws the following exception:

java.io.IOExcpetion: Failed to open http://www.google.com. Error Message: The system can not find the file specified.
        at sun.awt.windows.WDesktopPeer.ShellExecute(Unknown Source)
        at sun.awt.windows.WDesktopPeer.browse(Unknown Source)
        at java.awt.Desktop.browse(Unknown Source)
        at OpenBrowserTest.main(OpenBrowserTest.java:24)

Reproducible: Always

Steps to Reproduce:
1. Build the following Code using the attached build script
2. Copy the resulting EXE to %USERDIR%/AppData/LocalLow
3. Set FireFox as your default Browser
4. Execute the .exe file

Actual Results:  
Firefox does not open the URL.

Expected Results:  
Firefox opens the URL.
