    My runtime environment on the Options page is set to Java 15, so why does it say this at the top of my log?

    System Info: Java 1.8 (OpenJDK 64-Bit Server VM 25.222-b10) Host: Linux 4.4.0-164-generic (amd64)


    And this in the log?

    I'd say it's a bug in Paper.

    Are you sure that your server has Java 15 selected?

    Paper says it detected Java 8.

    You have to restart the server after changing the Java Version for the changes to take effect

    Sorry, I had multiple servers confused. But even though Java 8 is selected, how come the message at the top says 1.8? Is this the JDK version?
