Question

I am upgrading from OpenJDK-6 to OpenJDK-8 on an embedded platform and have problems with the fonts. We're using the DejaVu fonts. I have created a suitable fontconfig.properties file in the jre/lib directory, and when I list the fonts with java i get the list as follows:

DejaVu Sans
DejaVu Sans Condensed
DejaVu Sans Light
DejaVu Sans Mono
DejaVu Serif
DejaVu Serif Condensed
Dialog
DialogInput
Monospaced
SansSerif
Serif

The application in question is an AWT application - because it is running under PPC32 using the Zero JVM (haven't installed JamVM yet), but shows artefacts when rendering the fonts on the screen.

The issue looks like it is changing the background as well... The embedded system is running x11 7.7, with freetype, fontconfig, dejavu fonts.

How can I get the fonts to render correctly inside Java? I tried XFD, and that doesn't show any artefacts at all...

I'm sure I'm missing something, but haven't been able to find what...
