When you let your Eclipse IDE auto-organize your List/Map imports, it struggles with it and break …it’s a loss of productivity on every single file ! (ex: duplicate classes like List: java.awt.List, java.util.List and Map)

The Problem

‘Source -> Organize imports ‘ is not working for List or Map, an ask for user resolution (you), for each file ! But in Java, we only need java.util.List and java.util.Map. And these classes are massively used in Java projects.
