Hello.
I'm trying to upgrade from artemis 2.19 to 2.20 and see that for 2.20 I need to
use at least java 11:
> artemis create broker2
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/apache/activemq/artemis/boot/Artemis has been compiled by a more recent
version of the Java Runtime (class file version 55.0), this version of the Java
Runtime only recognizes class file versions up to 52.0

Accordingly to the latest documentation, java 1.8 is required version:
https://activemq.apache.org/components/artemis/documentation/latest/using-server.html
"Please note that Apache ActiveMQ Artemis requires a Java 8 or later."
So, is this statement in documentation outdated and for version 2.20 JDK 11 is
required?
Or is the distributive from Downloads is built using wrong compiler version?
