`close()` did not wait for the server thread to finish, so it could read stale state (`requestReceived`, `throwable`) while the thread was still running. This caused two intermittent failures: - "Never received a request": `close()` checked requestReceived before the server thread set it after accept() returned. - "Exception thrown while TlsHandshakeTimerOuter was running": the server thread got an expected IOException or BUFFER_UNDERFLOW when the client timed out and disconnected, and `close()` rethrew it. Fix: store the Thread reference and `join()` it in `close()` after closing the sockets. Remove the `requestReceived` and `throwable` checks since all server-side exceptions are expected (the client is designed to time out) and client-side assertions already validate correctness.
