OpenHAB2 + Razberry + Z-Wave Binding

It looks like I can get some feedback running the start_debug.sh. After doing so, and after editing the
([Solved] How to define a serial port on raspberry for openhab2 for my razberry zwave binding?)

setenv

in file “setenv” at /opt/openhab/runtime/karaf/bin
you need to add the parameter -Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0
just to make sure that karaf is aware on the JVM parameter.

for me those are now:

export JAVA_OPTS="${JAVA_OPTS}
-Dopenhab.home=${OPENHAB_HOME}
-Dopenhab.conf=${OPENHAB_CONF}
-Dopenhab.runtime=${OPENHAB_RUNTIME}
-Dopenhab.userdata=${OPENHAB_USERDATA}
-Dorg.osgi.service.http.port=${HTTP_PORT}
-Dorg.osgi.service.http.port.secure=${HTTPS_PORT}
-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0"

still no dice.

So is there another way to define the serial port in OH2?
