User Comments:
theshadow27: Clicked correct with the tooltip for the StringEqualsIgnoreCase.hint below

------- START SNIP ---------

<!description="String.equalsIgnoreCase is inefficient">
$f.equalsIgnoreCase($g) :: $f instanceof java.lang.String && $g instanceof java.lang.String
=> StringUtil.equalsIgnoreCase($f, $g);
;;
