Build ecChronos With Java 17 - Issue Ericsson#607

In order to provide support for Java 17 in EcChronos,
identify the minimal changes necessary for the project to
compile and run with Java 17. Additionally, implement these
changes and any necessary updates to Maven packages.

This change must be merged just after a release of ecChronos
with the Issue Ericsson#616 done.

Closes Ericsson#607
