[clamothebb]

@chrisryan10 I'm curious - Do you use this with Wire, or protobuf-java? I'd love to use Armeria with Wire, but ran into an issue when I tried.

[chrisryan10]

I've left the company now and retired, so I'm not sure what is the current state. We did have Wire in use, although personally I did not believe Wire was worthwhile overall.
