[jira] Resolved: (PIVOT-476) Bug in equals method in ArrayList and
LinkedList
Posted by "Greg Brown (JIRA)" <ji...@apache.org>.

Greg Brown resolved PIVOT-476.
------------------------------
Resolution: Fixed
Good catch. At first, I wasn't sure that changing the comparison to be type-agnostic was the right approach, but it seems like that's how the JDK List.equals() method works, so there's no reason not to be consistent.
Thanks.
