When creating a project, I specify java-7-openjdk in the JRE field. Without doing anything else, I create a class that calls Object.equals(Object o1, Object o2) added to Java7.
 public class Main { public static void main(String[] args) { boolean b = Object.equals(new World(), new World()); } } What I get
equals cant be resolved or is not a field
What did I miss?
