javax.swing.defaultlf - Not able to read the value of the secured property in windows.

        <j2se version="1.6+" java-vm-args="-Djavax.swing.defaultlf=VALUE"/>
  
Not able to read this property using System.getProperty("javafx.swing.default") which returns null value.

Again, This property is not appearign in
System.getProperty("jnlpx.vmargs");
As per spec all the secured properties will be part of System.getProperty("jnlpx.vmargs");

Here is the testcase: http://jdeploy01.india.sun.com:8080/JavawsMustangIntegTest/vmargs/propertiesJNLP/swingdefualt.jnlp

I see this problem in Windows. where as works fine in Mac.
