@J-N-K will this cause compatibility issues with OpenHAB? I know netty was/is an issue, and this is another package that OpenHAB also uses itself.

OpenHab can always choose to exclude dependencies. Locally updated mdns and it runs with no issues. Same with netty.
HAP-java also uses

org.zeromq curve25519-java 0.1.0

which can be deleted with no issues. (I've updated the other libs crypto deps locally too, maybe that's why. My favourate quote:
-"Works on my machine"
+"But we don't ship your machine, do we?" Don't know the original creator of that quote, sorry).

If you can update the deps with no issues, openhab can use the old stone age stuff if they choose to do so. It will still be compatible.

Really dislike not updating because of other projects. It's very well meant and carefull to OpenHab. But this way nobody moves.

openhab/openhab-core#1721
