Hi Antoine,

For all JVM related tests I've used the latest Early Access release at the time. For this article it should be some build of JDK 15.

I participate in the OpenJDK Outreach Program (https://wiki.openjdk.java.net/display/quality/Quality+Outreach) and I test each new JDK build with Apache Tomcat and Apache Wicket on both x86_64 and aarch64.
