Hi, I noticed read notifications for websockets are synced (connectionReadLock in WsFrameBase) although the only way it is called is through the read notification of the upgraded stream. Which means I don't see how any concurrency can occur.
However, writes are not synced (the equivalent sync would be in WsRemoteEndpointImplServer.onWritePossible) although there I believe there can be some concurrency. Similarly, the buffers field and the individual buffers could be at risk but it seems less likely. Did I miss something ? Rémy
