>                 URL: https://issues.apache.org/jira/browse/LANG-1260
>             Project: Commons Lang
>          Issue Type: Bug
>    Affects Versions: 3.4
>            Reporter: Philip Mundt
>
> When passing an invalid locale string ({{len != 2 && len != 5 && len < 7}}) to {{org.apache.commons.lang3.LocaleUtils#toLocale(String)}} the method would previously (3.1) throw an {{IllegalArgumentException}}.
> With version 3.4 the method will – at least for any string with {{len == 3}} – create an arbitrary locale:
> {code}
> // GIVEN
> String localeString = "xyz";
> // WHEN
> Locale xyz = LocaleUtils.toLocale(localeString);
> // THEN
> assertEquals(xyz.toString(), localeString); // What?
> {code}
> We are relying on this behaviour ({{IllegalArgumentException}}) and were quite surprised to not find any mention in the changelog.
