firefox java applet fails when the firefox is launched by a java program

Hi Support Team,

I run a simple Java program (a runnable jar file). The Java program code is as following

import java.io.IOException;
public class Main {
     public static void main(String args[]) throws IOException {
          //this website has a small Java applet inside
          Runtime.getRuntime.exec("firefox http://javatester.org/version.html");
          System.out.println("hello world");
     }
}

My JRE (yes, JRE, not JDK) is Oracle JRE 1.6.0_38.

What the program does is essentially opening http://javatester.org/version.html in Firefox. This website has a small Java applet, so performance won't be a problem. What happens then is that, Firefox is opened, http://javatester.org/version.html is opened, BUT the applet inside the website FAILS to play. The same thing happens if my Java program opens any other website which has applet.

However, if I run "firefox http://javatester.org/version.html" from command line, everything works perfectly. Similarly, if I open Firefox, then I type http://javatester.org/version.html at the URL field, everything also works perfectly.

This problem happens in Firefox, but NOT in Chromium (which I installed from your standard repository).

This problem doesn't happen in Oracle Linux distro. I haven't tried in other Linux distros, though.

Thank you

Fajrian Yunus
