---------------------------------------
Sure - just attached the rebased patch

> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.2.0

> Static code analysis is flagging cases of String.toLowerCase and
> String.toUpperCase being used without Locale. From the API reference:
> {quote}
> Note: This method is locale sensitive, and may produce unexpected results if
> used for strings that are intended to be interpreted locale independently.
> Examples are programming language identifiers, protocol keys, and HTML tags.
> For instance, "TITLE".toLowerCase() in a Turkish locale returns "t\u0131tle",
> where '\u0131' is the LATIN SMALL LETTER DOTLESS I character. To obtain
> correct results for locale insensitive strings, use toLowerCase(Locale.ROOT).
> {quote}
> Many uses of these functions do appear to be looking up classes, etc. and not
> dealing with stored data, so I'd think there aren't significant compatibility
> problems here and specifying the locale is indeed the safer way to go.
