Build: NetBeans IDE Dev (Build 201607250002)
VM: Java HotSpot(TM) 64-Bit Server VM, 25.31-b07, Java(TM) SE Runtime Environment, 1.8.0_31-b13
OS: Linux

User Comments:
helderneres: Using refactoring to implement a abstract method from a interface that is already implemented with same signature except return type. The @Override annotation were present in the refered method.

jockel: While refactoring: pressed alt+insert to implement an abstract method (where another method with same name but another return type was still there and not deleted before)

GUEST: I didn't remember. :(
