[jira] [Commented] (LANG-686) StringUtils.replaceEachRepeatedly("aaa", new String[]{"aa"}, new String[]{"aXa"}); throw an exception

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

    [ https://issues.apache.org/jira/browse/LANG-686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13071526#comment-13071526 ] 

Henri Yandell commented on LANG-686:
------------------------------------

Digging into this, the search should have been:

"aaa"
"aXaa"
"aXaXa"

Which is hardly the deepest loop.

The TTL would have been 1, ie) the length of the inputted String[] { "aXa" }.

I wonder if the issue is that TTL needs to be longer (which is what qed did by adding extra ""s).
