[BUG] Error while logging in about minecolab HOT 2 CLOSED

Hello Polikopp! Thanks for opening an issue.
I have never stumbled across this error during my testing. Looks like its depends on the hardware available at that time.
Cay you try to edit your server.properties and change use-native-transport to false? It might result in slightly lower performance, but not noticeable.
ps: If you are wondering what it does, its just some linux server performance improvements by optimizing packet sending/receiving. Several people seem to have problem with it on certain restricted hardwares, so this might work.

Hello, thank you for your answer. I changed the value but it didn't change anything. After some research and some tests, by putting java 8, it worked. So I'm going to leave java 8 for now.
