Environmental Variable Not Reading in Java

I am using Ubuntu 12.04. In my user home, I added one environmental variable to .bashrc file.

export MYCONFIG_HOME=/home/myuser/config-1.0

And I run the .bashrc file

source ~/.bashrc

I open my STS, added the following code

public static void main(String[] args) {
        String myHomeVar = System.getenv("MYCONFIG_HOME");
        System.out.println(System.getProperty("user.name"));
        System.out.println(myHomeVar);
    }

It gives me following output

myuser
null

When I do echo $MYCONFIG_HOME, it is giving the value. Why is it not getting in the Java program?

Do I need to restart the system? If I have to restart, is there anyway to get the value without restarting the system?

NOTE: It got worked when I restarted the system.

maybe sts forks its own process, and hence does not inherit your shell params. – Niels Bech Nielsen Jul 08 '14 at 07:32
So what I have to do? restart? – iCode Jul 08 '14 at 07:41
Are you launching STS from the same command line where you do the `echo $MYCONFIG_HOME`? – Andreas Fester Jul 08 '14 at 08:52
Nope. It's different. I set the value after starting the STS only. I tried restarting STS. It didn't work. Till now I haven't tried restarting system. – iCode Jul 08 '14 at 09:07
It got worked when I restarted the system. – iCode Jul 08 '14 at 10:32
I think you should restart your system, three times to make sure. – vikingsteve Jul 08 '14 at 10:35
I once restarted and it's working. But my question is why the system needs to restart. Any problem with STS? – iCode Jul 08 '14 at 12:25
