- Make sure parent poms provide maven plugins supporting Java 9, 10, 11...
- validate through release lifecycle (how we missed the issue with site-plugin last time)
- Find where this triggers compile issues (as in mvn test-compile), without tests
- Pave the way for modern test execution
- on JDK9+ (more effort, mockito 2 upgrade, etc.); file tickets
- using JUnit5, running both new/old tests with both jupiter/vintage engines
