When compiling following class

import java.util.ArrayList;
import java.util.List;

public class CompilerNullPointerTest {
	List someList = new ArrayList();
	public ArrayList getSomeList() {
		return someList;
	}
}

I get the following NullPointerException with M3. When changing 
List someList = new ArrayList();
to
List<Object> someList = new ArrayList<Object>();
I get the expected "Type mismatch: cannot convert from List<Object> to
ArrayList" error message.
