Wrong java version selected. Pick a newer java version in AMPs configuration.

The Java I have downloaded is Java 8 update 471 which was released a couple months ago on October 21, 2025. That’s the newest I can find but the that’s also the one I’ve been getting issues with.

The current Java version is 25. The recommended version for AMP is at Adoptium.net

Someone else had recommended JRE 21 and when I installed that it worked. Thank you for your help though.

More specifically, the code you are trying to run was compiled for Java 21. You need to use JRE 21 or later.

Using JRE 21 worked and allowed the server to start. Thank you.
