--- Comment #14 from Barry Coughlan <b.coughl...@gmail.com> ---
I can reproduce this on 8.0.29. I will create a proper test case that doesn't
need breakpoints during the week.
Reproduced with the following:
@OnMessage
public void onMessage(Session session, ModelObject msg) {
try {
session.getBasicRemote().sendText("Test"); // <-- Breakpoint here
} catch (IOException e) {
e.printStackTrace();
}
}
1. Open websocket connection to the server
2. Send message from client to server, hits the breakpoint
3. Close the connection
4. Continue from the @OnMessage breakpoint
The following happens:
- Step 4 throws an exception as expected (java.io.IOException: An established
connection was aborted by the software in your host machine) (we catch and log
this exception)
- @OnError is called with a java.nio.channels.ClosedChannelException:
