Re: UUID JSON serialization issue

Hi,

UUID is not required to be supported by the JSON-B spec =
(https://jakarta.ee/specifications/jsonb/3.0/jakarta-jsonb-spec-3.0#defaul=
t-mapping), so Johnzon does not implement it. As far as I can tell from =
skimming over filenames in yasson it seems like they do however support =
it, hence your example works everywhere else (AFAIK TomEE is the only =
application server that uses Johnzon)

You need to create a JsonbAdapter for this to reliably work and register =
it either globally in JAX-RS with a ContextResolver<Jsonb> (this could =
cause issues e.g. in tests/when you use the models outside of JAX-RS) or =
use it in your model classes with @JsonbTypeAdapter which is what I =
would prefer


Thanks

Markus
