Hello there! I faced a warning issue when I called client.shutdown().

I really appreciate your contribution to this library. Looks forward to getting the fix for future release.

Best Regard,

Thank you for reporting. Which jdk are you using?

kpavlov commented 4 years ago

I can reproduce it under JDK8 but it works on JDK11 and JDK14. I'm considering dropping support for JDK8 as it is officially deprecated.

kpavlov commented 4 years ago

Warning appears under Netty v.4.1.44.Final+. Under Netty 4.1.43 I can't reproduce it.

kpavlov commented 4 years ago

Workaround is to downgrade Netty to 4.1.43. I will upgrade min JVM version to 11 in next release.
