[jira] Commented: (LANG-412) StrBuilder appendFixedWidth does not handle nulls

["Henri Yandell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568433#action_12568433 ] 

Henri Yandell commented on LANG-412:
------------------------------------

Confirmed (visually). As appendNull's effect is to do nothing if it is set to null, my assumption is that having nullText be null is merely an optmization for the empty String.

So I think the solution will be to make the fixed width methods use an empty string if they get back a null nullText.

> Appending a null value with fixed width causes a null pointer exception if getNullText() has not been set.
