Please try with OpenJDK 8.

Please try with OpenJDK 8.

It does run with Java 8, but the "Class not found" error still exists. No problem?
BTW, why cannot we use higher version of Java for a better performance

I can confirm this issue, both in target/akarin-1.16.5-launcher.jar and Akarin-Server/target/akarin-1.16.5.jar, so it maybe something related to maven shade plugin?

#215 this pr breaks something but I don't know how, can you build it with Java 8 and then run on Java 11? @liups233

However I can build on windows, I don't know why it errors on ubuntu.
