> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.2.6
> Environment: Observed on karaf (jetty).
> Reproduced on jetty by modifying cxf SSE tests.
> Reporter: Lukasz Wysocki
> Priority: Major
> Attachments: cxf-7874.reproduce.patch

>
> Closing of SSE connection by client is not detected and handled on the server
> part.
> This results in server leaking resources when it is the clients
> responsibility for deciding on the lifetime of SSE connection.
> Scenario is status notifications of devices are sent to client (browser),
> this is a continues stream that lives until browser tab/window is closed,
> which results in client end closing the underlying connection.
> SseSinkImpl is not informed of connection being closed.
> At the same time exception set on future in
> org.apache.cxf.jaxrs.sse.SseEventSinkImpl#dequeue in case of channel being
> closed is not acted upon internally within SseSinkImpl.
