[jira] [Commented] (LANG-1070) confusing example in ArrayUtils.add()

["Benedikt Ritter (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14229190#comment-14229190 ] 

Benedikt Ritter commented on LANG-1070:
---------------------------------------

The current behavior of {{add(T[], T)}} seems to be inconsistent with the various varargs methods. For example calling {{addAll(boolean[], boolean...)}} with null will return null. So maybe instead of changing the docs, we should let {{add(T[], T)}} simply return null for null inputs. WDYT?

>    Affects Versions: 3.3.2

>            Priority: Trivial

> Method documentation claims that
>     ArrayUtils.add(null, null)     = null
> However, this is not true since this parameter combination leads to an exception.
> Either remove this line from documentation, or rewrite it to explicitly mention the exception. Maybe there are other related methods with similar problem in the docs.
