Hi,

At one point, the handler iterates over ReactiveTypeHandler#JSON_STREAMING_MEDIA_TYPES which contains two values: MediaType.APPLICATION_NDJSON and MediaType.APPLICATION_STREAM_JSON.

If a controller uses a custom vendor-specific "produces" streaming type such as application/vnd.myname.v1+x-ndjson (for API versioning for example), it won't "match" within the loop and the handler will not use a JsonEmitterSubscriber as expected.

Shouldn't ReactiveTypeHandler#JSON_STREAMING_MEDIA_TYPES contain the generic media type: application/*+x-ndjson so that it "includes" custom vendor-specific streaming type.

Thank you.

Hi there,
Any update on that one ?

I have discussed that one with the team and it appear a bit overcomplicated to add a customization path for that particular aspect. we agree that your suggestion of adding a wildcard subtype for that particular component is an acceptable middle ground.

Polish ReactiveTypeHandler when checking wildcard ndjson subtype
3f14ebc 
This commit polishes the previous change, ensuring that if the request
uses a wildcard subtype with an ndjson suffix then the wildcard isn't
present in the response's Content-Type.

Insteand, in that case we would fall back to `applicatin/x-ndjson` (the
base ndjson media type), assuming that the requester is only interested
in the ndjson nature of the underlying representation and not in the
specific semantics of any subtype.
