with this patch I was finally able to make a debug build. And the error 
message is much improved now:

# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc: 
SuppressErrorAt=/templateInterpreter_x86_64.cpp:170
#
# A fatal error has been detected by the Java Runtime Environment:

is it possible the demo code does not work on x86, or maybe it is only 
amd64?
