Description

The vote on 1.18.0-rc2 revealed that we don't do proper JDK version enforcement in release profile of the Maven build.

This is added to ensure that Java 8 is used when releasing the artifacts. The current configuration sets the version as a "soft" requirement (see documentation on version which is referenced in the Maven Enforcer Plugin website).

We should use square brackets to enforce the JDK version. The same can be applied to the Maven version.
