Deprecate Java 8 and move to Java 11 #222
Description
Right now we support all Java version starting on Java 8.
Soon, we will have to move towards Java 11 as some of our dependencies are no longer supporting Java 8 (e.g., mockito, spoon).
The issue with this is that some benchmarks, including https://github.com/rjust/defects4j, require Java 8.
