Java 19 compatibilty.

[Bram Stolk]

Is this remapper compatible with java 19?

Because when I use net.md_5.specialsource.mavenplugin version 1.2.4, I get the error:

Unsupported class file major version 63

The full error from the remap stage:

Doesn't Mojang specify a minimal version, or later? If so, why would jdk-1.19 not work?

OS: Ubuntu 22.04.2

JDK: openjdk-19-jre-headless:amd64 19.0.2+7-0ubuntu3~22.04

The latest dev build supports up to Java 20, the Maven release does not. I will prepare a release soon

It is recommended you code plugins using Java 17, the latest LTS release and recommended Java version.

Ok, I tried the unreleased 1.11.1 instead, and that indeed works with Java 19.

Thank you!
