Will wait until confirmation from Redoute that 11 is nice to proceed.

As a reference and for debug purpose:

49 = Java 5 50 = Java 6 51 = Java 7 52 = Java 8 53 = Java 9 54 = Java 10 55 = Java 11 56 = Java 12 57 = Java 13 58 = Java 14 59 = Java 15 60 = Java 16 61 = Java 17 62 = Java 18 63 = Java 19 64 = Java 20 65 = Java 21

in case you get: Caused by: java.lang.UnsupportedClassVersionError: org/cerberus/core/config/CerberusConfiguration 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 (unable to load class [org.cerberus.core.config.CerberusConfiguration])

That means that commilation was made with java 11 and runtime is in java 8.
