What methods should go into a java.util.Objects class in JDK 7?

For JDK 7, I think it is high-time the platform included a class like
java.util.Objects to hold commonly-written utility methods. For
example, a two-argument static equals method that returned true if both
arguments are null, returns false is one argument is null, and otherwise
returns the result of calling arg1.equals(arg2) (6797535 "Add shared
two argument static equals method to the platform").
A static hashCode method returning 0 for null and the value of
arg.hashCode() has also been suggested.
A set of
static int compareTo(int, int)
static int compareTo(long, long)
methods probably belongs somewhere in the platform too.
What other utility methods would have broad enough use and applicability
to go into a common java.util class?
