• Update Netty to v4.1.1.Final, which is the first stable release we've released with. gRPC-java v0.14.0 was already compatible with Netty v4.1.1. This fixes cancellation causing Channel to black hole received data and fixes a DoS bug in renegotiation when using OpenSSL-based tcnative (BoringSSL not impacted).
• The Netty version bump also supports the "fat" tcnative-boringssl-static JAR that has binaries for all platforms. Simply depend on 1.1.33.Fork17 without any OS-specific classifier
• Reworked shutdown handling for OkHttp. Fixes "IllegalStateException: Listener is still attached to activeTransport. Seems transportTerminated was not called."
