Wildfly 13 to wildfly 17 json serialization

I have problem in serialization of Pojo to JSON.
I have a Provider that impelments ContextResolver<ObjectMapper>.
That constructor is called regulary on deploy, but the method getContext is never called, so my custom serialization registration is never called.
What's changed at json serialization level between 13 and 17?
If I copy yasson-1.0.1 from wildfly 13 and swap it with yasson-1.0.3 (wildfly 17) everything works fine.
Thank you very much
Regards
