Also got an endless bunch of these: 

2020-01-26 20:39:25.604 [ERROR] [ab.binding.bluetooth.BluetoothDevice] - Failed to inform listener 'org.openhab.binding.bluetooth.am43.internal.AM43Handler@1147f0c': null

It appears as if a scheduled future wasn't canceled? Even though the code clearly indicates to cancel it...

I`m wondering if this is still an issue as it is three years old. I see several PR's since this issue and last week i tried to improve the null handling by PR: https://github.com/openhab/openhab-addons/pull/13979

If this is still an issue, could you verify if it is solved (or still happening) by those bluetooth PR's?
