-------------------------------------
Summary: String case conversions are locale-sensitive, used
without locale
Key: HBASE-15889
URL: https://issues.apache.org/jira/browse/HBASE-15889
Project: HBase
Issue Type: Bug
Affects Versions: 1.2.0
Reporter: Sean Mackrory
Priority: Minor
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.
