3.1
here's a case where eclipse generates 5 errors for 1 mistake and all are not
very helpful. When it happened to me I ran javac to understand what's going on.
They show 1 message and it tells you exactly what's wrong.

public class A<T0> extends ArrayList<T0> implements I<T0>{
}
interface I<T1> extends Collection{	
}

Eclipse error message (1 of 5):
Name clash: The method addAll(Collection<? extends E>) of type ArrayList<T0> has
the same erasure as addAll(Collection<? extends E>) of type Collection but does
not override it	

javac error message (1 of 1):
java.util.Collection cannot be inherited with different arguments: <> and <T0>
public class A<T0> extends ArrayList<T0> implements I<T0>{
