I recently set up a Minecraft server on a debian10 root server and when I started it came that
> WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by io.netty.util.internal.PlatformDependent0 (file: /home/Minecraft-Server/bukkit.jar) to field java.nio.Buffer.address WARNING: Please consider reporting this to the maintainers of io.netty.util.internal.PlatformDependent0 WARNING: Use --illegal-access = warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release
After that the server started and I wanted to connect to it, but whenever I want to connect, this message is spam into the console
[11:17:44 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.

Can someone please help me here?
Looks like Java is not installed or is installed incorrectly on your server.
I also had such an error with the io.netty.epoll
Which Java version is installed?
Which one do I need?
Java is installed with apt install jdk or so it was
I believe
Openjdk 11.0.7 2020-04-14
OpenJDK Runtime Environment (build 11.0.7 + 10-post-Debian-3deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.7 + 10-post-Debian-3deb10u1, mixed mode, sharing)
Then I would check which Java version is installed.
Minecraft servers actually need Java 8 as far as I know
Try Java 8
