the only reason for this I can think of is that you might not use the required netty-tcnative* version

That was my first thought, but I didn’t have a chance to check. Every time I update netty - I don’t know if I have to update tcnative, and if yes - what version should I use. During a single netty release, sometimes few tcnative releases are done, so it’s always an unknown thing for me.

@doom369 see https://github.com/netty/netty/pull/12490

Looks good.

Just depend on netty-bom ? This will ensure the right version is used
