java.awt.Desktop.getDesktop causing java.lang.NullPointerException

Karanbir Dhillon-Oracle

JRE Version - 1.0.8_91 and Code partial line ..for a JavaFX Application which is throwing error.

Code

---------

java.awt.Desktop.getDesktop().browse(new URI("http://www.oracle.com"));

It runs in all Users Machine except one where the exception thrown is as below it is a Windows 7 machine. Tried to change the default browser from Eg Firefox to IE but no change in the Error. Tried to go to run and example go to http://www.oracle.com it opens in the default browser on the machine and changing the default browser does show affect right away.

Any Advise on the same,  tried Uninstall & Reinstall of JRE but it did not help. As per Doc Desktop (Java Platform SE 8 ) it does not say anything to get such Exception.
