[jira] [Commented] (VELTOOLS-136) SortTool fails on null values

["Christopher Schultz (Commented) (JIRA)" <de...@velocity.apache.org>]

    [ https://issues.apache.org/jira/browse/VELTOOLS-136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13197024#comment-13197024 ] 

Christopher Schultz commented on VELTOOLS-136:
----------------------------------------------

Did you mean that SortTool doesn't accept null collections, or does not accept collections which contain null elements?

If the latter, where do you expect null elements to go? The end of the list? The beginning?

> The sort tool uses "comparison = right.compareTo(null);" on line 276. That can fail in the case the right object compareTo() method can
> not handle null params. I.e. java.util.Date can not handle that, so the sort result is empty. The sort tool should support sorting of collections with
> null values.
