I successfully compiled and tested it for/on an ARMv7 Cortex A9 CPU:
# /usr/lib/jvm/java-8-openjdk/jre/bin/java -version
openjdk version "1.8.0-internal"
OpenJDK Runtime Environment (build 1.8.0-internal-leri_2015_08_28_08_47-b00)
OpenJDK Zero VM (build 25.60-b23, interpreted mode)

Also X11/awt/swing works fine! Only problem for me is that ZeroVM is
running in "interpreted mode". Therefore my programs are running really
slow.

Was the "mixed mode" available/working in your tests?

IMHO a working JIT (=> mixed-mode) is a must-have for merging this patch
upstream. What do you think Otavio?

thanks & regards,
Richard L
