The Java version check is good, but why enforce Java 21 when Matchbox still supports Java 11?

Hello @davidouagne , The current version of the matchbox project uses JDK 21 and is compiled with Java 21, as specified by <maven.compiler.release>21</maven.compiler.release> in the Maven configuration.
However, the documentation has not yet been updated it seems.

Do you know if it’s possible to build Matchbox with an earlier version such as Java 17?

Is it possible to configure a CI/CD pipeline with the Java version as a parameter?

It may be necessary to have good control over the Java version, as other users are using Java 17 instead of 21.

There is a warning message when using java 17 :

and validation don't work, but everything work well with java 21.
