Cannot stop server with gRPC service in 0.97

Hi guys,

Could be red herring but I was playing with Armeria 0.97 a bit (like it was recommended in https://github.com/line/armeria/issues/2319). It looks like that that I can’t stop a server with single gRPC service, line (1) from the code below never returns.

ServerBuilder sb = new ServerBuilder();
    Server server =
        sb.service(new GrpcServiceBuilder().addService(new PingService()).build())
            .port(1234, SessionProtocol.HTTP).build();

    CompletableFuture startFuture = server.start();
    startFuture.join();

    CompletableFuture stopFuture = server.stop();
    stopFuture.join(); //  (1)

The same code worked fine in 0.88.

Sincerely, Andrey

PS. The test is executed from IntelliJ Idea 2019.2 on openjdk 12.0.2+10

After some tests it looks like that minor version of Netty makes all the difference

• Armeria 0.88 works fine with both 4.1.42.Final and 4.1.43.Final.

• Armeria 0.97 works with 4.1.43.Final but for some reason I can’t stop server on 4.1.42.Final and below (4.1.41.Final doesn’t work as well). “Luckily” my project is on 4.1.42.Final.

Can you try this?

Let me close this issue. If you have a problem with stopping a server, feel free to reopen this.
