For dev environment you can set java.rmi.server.hostname to the catch-all IP address 0.0.0.0

Example:

 -Djava.rmi.server.hostname=0.0.0.0 \
                -Dcom.sun.management.jmxremote \
                -Dcom.sun.management.jmxremote.port=${JMX_PORT} \
                -Dcom.sun.management.jmxremote.rmi.port=${JMX_PORT} \
                -Dcom.sun.management.jmxremote.local.only=false \
                -Dcom.sun.management.jmxremote.authenticate=false \
                -Dcom.sun.management.jmxremote.ssl=false
