}

Example 8 with ChannelHandler

use of io.netty.channel.ChannelHandler in project grpc-java by grpc.

the class ProtocolNegotiatorsTest method tlsAdapter_exceptionClosesChannel.

@Test
public void tlsAdapter_exceptionClosesChannel() throws Exception {
    ChannelHandler handler = new ServerTlsHandler(sslContext, grpcHandler);
