Using a setup like below... interface API { @Produces( "text/event-stream" ) @GET @Path( "events" ) void events(@Context SseEventSink sseSink, @Context Sse sse); } class APIImpl implements API { void events(SseEventSink sseSink, Sse sse) { active.saveForLater(sseSink, sse); } } The error seems to be located at SseEventOutputImpl.java:116. It uses method.getMethod().getAnnotation(). Which doesn't look for inherited annotations. The fix appears simple. "method" which is a "ResourceMethodInvoker" already has all the inherited annotations gathered. It just needs to be checked in place of the current.
