oksse | extension library for OkHttp to create a Server-Sent Event | Notification library

I'm trying to create a client that can receive events from a server using SSE (server-sent events) and I'm using OkHttp3 to do that, combined with the OkHttp3-sse library (com.squareup.okhttp3:okhttp:4.1.0 & com.squareup.okhttp3:okhttp-sse:4.1.0). I am able to connect to the server and receive the events just fine, but at some point in time, I want to disconnect the client and shutdown my application. That is were the problem is. The connection gets closed, but the application is not shutting down, probably due to the ConnectionPool not closing.

As there is hardly any documentation on the use of the OkHttp3-sse library, I have tried to reverse engineer from the code what to do. I have tried to:

• call RealEventSource.cancel() which is disconnecting, but is hanging on a thread
• call OkHttpClient.dispatcher().cancelAll() which is also disconnecting, but remains hanging on a thread
• call Response.close() which is passed to EventSourceListener.onOpen()

As an alternative, I have looked at https://github.com/heremaps/oksse which has the RealServerSentEvent.close() call which is doing what I expect. It closes the connection and stops all threads allowing the application to shutdown completely. I have looked at the implementation of the RealServerSentEvent class to see how the implementation differs from RealEventSource. I think the difference is in the conditions of the read loop:
