-------------------------------

             Summary: Switch to Apache Commons Collections 4.0
                 Key: ROL-1994
                 URL: https://issues.apache.org/jira/browse/ROL-1994
             Project: Apache Roller
          Issue Type: Task
    Affects Versions: 5.1
            Reporter: Glen Mazza
            Assignee: Roller Unassigned
            Priority: Minor


In five places we're using a nongeneric "ReverseComparator()" causing IntelliJ 
idea complaints that we're doing an unchecked assignment.  Commons Collections 
4 supports generic types: 
https://commons.apache.org/proper/commons-collections/release_4_0.html, 
https://commons.apache.org/proper/commons-collections/javadocs/api-release/org/apache/commons/collections4/comparators/ReverseComparator.html.

A better fix might be to stop using this library altogether and just rely on 
what the JDK provides, if possible.
