openHAB serial dependency : how does it work?

I think users would be happy to be able to use that as an additional option based on
Can I use “/dev/serial/by-id”?.

You can probably already use them because the RXTX serial transport will add any configured device path to the list of ports in gnu.io.rxtx.SerialPorts .

But I read there is a bug which crashes the JVM which currently prevents using long device names.

First of all thanks for the development of openHAB and the Zigbee binding, it’s a great piece of software I just upgraded to OpenHAB 3.3 running on an Ubuntu 20.04 system (apt installation). My system sometimes changes the assignments of the USB ports to the tty devices, i.e. sometimes the Zigbee stick will be at /dev/ttyUSB0 and sometimes /dev/ttyUSB1. So I changed the device to a symlink that always resolves to the right device: /dev/serial/by-id/usb-Silicon_Labs_BV_2010_10_01382705-if0…

So I think after upgrading nrjavaserial to a version that has the fix the only missing part is adding these identifiers to the discovered port identifier list so they can be more easily configured?
