]
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
> StringUtils JavaDoc contains erroneous examples

> These results are wrong:
