Probably yes, but your scenario might even be enough to justify it.
I would be happy to contribute some code if it improves portability between

Sure, feel free to work on that and send a PR.

OK, good, I hope that can offer some idea for integrating.

RESTEasy and need of Accept header
by Rostislav Svoboda
Hi.
I played a bit with SSE, example based on https://www.youtube.com/watch?time_continue=8&v=qQLVCgmiMgQ
Code is here https://github.com/rsvoboda/rsvoboda-playground/tree/master/ee8-sample-sse
For GlassFish 5 I could do just: curl -i http://localhost:8080/ee8-sample-sse/resources/beats
But for WF I had to specify Accept header: curl -i -H "Accept: text/event-stream" http://localhost:8080/ee8-sample-sse/resources/beats
When I used curl command which was working on GlassFish 5 I received pretty nasty NPE stacktrace.
These days people are playing quite a lot with new stuff in EE8, they are using GlassFish 5 and composing their clients (Java, JavaScript, curl / libcurl ) based on this experience (who reads the spec ? when you have RI you can trust;) ).
RESTEasy requirement on Accept header can be pain you_know_where for migration towards JBoss world.
For sure the error message should be more user friendly and more descriptive.
And I would also vote for more RI like behavior in this case. WDYT ?
NPE details:

Context Path:
/ee8-sample
Servlet Path:
