> The class {{org.apache.cxf.jaxrs.sse.SseBroadcasterImpl}} does not uphold the contract stated in {{javax.ws.rs.sse.SseBroadcaster}} interface.
> The registered {{onError}} and {{onClose}} callbacks are not called when {{SseEventSink}} is closed or there is an communication error/timeout.
> It seems the problem can be pinpointed to anonymous implementation of {{AsyncListener}} registered in {{AsyncContext}} from {{SseBroadcasterImpl.register}} method (GitHub link [HERE|https://github.com/apache/cxf/blob/8eab54c2a285ac91b0a04b8cd7e899d45f15b73a/rt/rs/sse/src/main/java/org/apache/cxf/jaxrs/sse/SseBroadcasterImpl.java#L55]).
> Seems like extending the {{onComplete}} and {{onTimeout}}/{{onError}} methods to do additional calls to {{closers.forEach}} and {{exceptioners.forEach}} might solve this.
