NPE at sun.awt.X11FontManager.getDefaultPlatformFont

[Enric Jaen]

Hello, 

I have installed:

java version "1.7.0_09-icedtea"

OpenJDK Runtime Environment (rhel-2.3.3.el6_3.1-i386)
OpenJDK Server VM (build 23.2-b09, mixed mode)


and I receive the following NullPointerException, and I guess it's an issue with OpenJDK. Any idea?



java.lang.NullPointerException
