Yes. Java does I/O on a separate thread, and that thread notices the broken TCP connection. On Mon, May 6, 2019 at 8:13 AM Isuru Samaraweera wrote: > So it seems breaking of TCP connection is detected by a separate thread > than the main thread right? > > > On Mon, May 6, 2019 at 8:39 PM Eric A

When the TCP connection is detected to be broken, all RPCs on that connection are cancelled. This calls context.cancel() . That immediately does two things: changes the boolean that isCance
