Please look at the following code :

public class A {
	
	public void doSomething(List aList) {}
	
	public void doSomethingElse(List<Integer> aList) {}
}

public class B extends A {

	public static void doSomething(List aList) {}
	
	public static void doSomethingElse(List<String> aList) {}
}

In class B eclipse marks method doSomething(..) with this error message:

"This static method cannot hide the instance method from A"

According to JLS this is correct:

http://java.sun.com/docs/books/jls/third_edition/html/classes.html#8.4.8.2

But the same should happen with method doSomethingElse(..) in class B, because after type erasure this method hides doSomethingElse(..) from class A.

Compiling class B with javac from Sun JDK (1.5.09) produces a compiler error.

Interestingly after changing the type parameter of aList in Method B.doSomethingElse(List<String> aList) to Integer eclipse produces the same compiler error as in the first example.
