Test project for Micronaut WebSocket @OnClose handler
The problem
@OnClose is not called for WebSockets in bad network environments with lots of dropped packets
micronaut-projects/micronaut-core#8493
Tools we use
clumsy - https://jagt.github.io/clumsy/ to make your network condition on Windows significantly worse in a controlled way
Repro steps
1. Start the server.
2. Start the client.
3. Configure clumsy to drop 50% of the packets and use filter tcp and (tcp.DstPort == 34242 or tcp.SrcPort == 34242).
4. Press "Start" button on clumsy.
5. Kill the client (python).
Actual Behavior
OnClose handler is NOT called when the python process is killed and the TCP Connection is destroyed.
Expected behavior
OnClose handler would be called.
