> Methods like {{org.codehaus.groovy.runtime.DefaultGroovyMethods.sort(Iterable<T>, boolean, Comparator<T>)}} and all the others alike should be changed to accept a {{Comparator<? super T>}}, otherwise if you use {{@CompileStatic}} you'll get compiler errors as soon as you try to sort an Iterable/Collection using a comparator that accept superclass instances.
