code-style UseLocaleWithCaseConversions (PMD)

When doing a String.toLowerCase()/toUpperCase() call, use a Locale

When doing a String.toLowerCase()/toUpperCase() call, use a Locale. This avoids problems with certain locales, i.e. Turkish.

    
class Foo {
 // BAD
 if (x.toLowerCase().equals("list"))...
 /*
 This will not match "LIST" when in Turkish locale
 The above could be
 if (x.toLowerCase(Locale.US).equals("list")) ...
 or simply
 if (x.equalsIgnoreCase("list")) ...
 */
 // GOOD
 String z = a.toLowerCase(Locale.EN);
}
