Do you still have a zwave binding manually installed through your addons folder?
I installed z-wave binding through paperUI, it was updated to 2.5.0 together with openhab.
bundle:list|grep -i zwave*
276 │ Active │ 80 │ 2.5.0 │ openHAB Add-ons :: Bundles :: ZWave Binding
Will try now to update to latest snapshot version
