Description
This error is spammed in the logs over and over again when trying to start a spigot 1.11 server using Java 9
[15:05:47] Netty Epoll Server IO #1/WARN: An exceptionCaught() event was fired, and it reached at the
tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
java.lang.RuntimeException: Unable to access address of buffer

1. Java 9 is only in beta
2. Netty is not updated on java 9
3. As written in the spigot wiki, its recommended to use java 8
"Keep in mind that Java 8 is the recommended Java version for all Minecraft applications."

You can report this to Mojang - bugs.mojang.com

This is assuming there even exists a Java 9 compatible version of Netty which I am unsure of.
That should be checked first.

No netty version supports java 9, but you can set use-native-transport=false in server.properties
to make it work.
Note that Java 9 is completely unsupported and will likely cause heaps more bugs.
