NPE at sun.awt.X11FontManager.getDefaultPlatformFont

[Pavel Tisnovsky]

Hi Enric,

I seen this failure on 32bit OpenJDK/IcedTea installed on 64bit system.
The problem was caused by wrong architecture (i386/x86_64) of libfreetype
library. If you have 32bit JDK @ 64bit RHEL, please make sure the
libfreetype is 32bit/i386 too.

Cheers,
Pavel
