The question posed to the MP team does not really match the question posted here, and seems to be a tangental ask.
The problem is this line of code [1], and nothing to do with TomEE's behavior; it defaults to JSON even though the spec states it should be YAML. Perhaps a clean solution would be to make this a config setting? But seems like there's a missing TCK test as well. I'd also question when a browser goes here, what does it send in the Accepts header. My guess is most modern browsers send text/html which also wouldn't line up.
