New to Java

Hi friends,

This is a stupid issue, I am not able to solve sice almost two days.

A simpl app throws this exception:
Caused by: java.lang.NullPointerException
at sun.awt.FontConfiguration.getVersion(Unknown Source)

I dont know why the hell should it come.
Is it related something to fonts.
Even the least of help will be highly appreciated.,

thanks
