openhab-addons: [smartmeter] Binding causes openHAB to crash

I’ve installed openhab 2.4 stable.

When i define a sml reader thing (smartmeter 2.4 binding) my complete openhab crashes and restarts itself. This happens as long as the thing exists (openhab start -> 30 seconds -> openhab restart). When i delete the smartmeter sml thing everything is fine.

I went back and deleted the new smartmeter binding and installed a jar for openhab 2.3 from marketplace smartmeter binding -> Everything runs smooth with this.

Current Behavior
