Subject [jira] Closed: (LANG-631) StringUtils JavaDoc contains erroneous examples
Date Tue, 06 Jul 2010 07:28:50 GMT

     [ https://issues.apache.org/jira/browse/LANG-631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Henri Yandell closed LANG-631.
------------------------------

    Resolution: Fixed

Current trunk had addressed this, but had transposed the 4 and 5 results. I've fixed that
in r960831, namely:

     * StringUtils.lastIndexOf("aabaabaa", "a")  = 7
     * StringUtils.lastIndexOf("aabaabaa", "b")  = 5
     * StringUtils.lastIndexOf("aabaabaa", "ab") = 4
