The new Objects class

Just seen the new Objects class in the java.util.
I'd like to ask why does the
public static int *hash*(Object... values)
method, has the warning: *
Warning: When a single object reference is supplied, the returned value does
not equal the hash code of that object reference.* This value can be
computed by calling
hashCode(Object)<http://download.java.net/jdk7/docs/api/java/util/Objects.html#hashCode%28java.lang.Object%29>
.
When it could be rewritten as :
public static int *hash*(Object value1, Object value2, Object... restOfValues)
to avoid that.
