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);
;;

------ END SNIP --------

I should file a general RFE on the inspector system in general, but that is a seperate topic all together.

Comment 2 Jan Lahoda 2013-04-03 17:40:57 UTC 
Conversion from expression to expression statement works the same as conversion from the expression into the embedded expression from the statement after this change:
