Mauro Molinari created GROOVY-7976:
--------------------------------------
Summary: Sort methods that accept a comparator should allow
Comparator<? super T>
Key: GROOVY-7976
URL: https://issues.apache.org/jira/browse/GROOVY-7976
Project: Groovy
Issue Type: Bug
Components: groovy-jdk
Affects Versions: 2.4.7
Reporter: Mauro Molinari
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.
