java.lang.String#contentEquals(CharSequence) suboptimal?

[Ulf Zibis]

I agree, this would be a short cut in case of cs is not a String.
In case of cs is a String, user likely would have used the standard 
equals() method to avoid the double check by instanceof.
In case of HotSpot compilation AND inlining, there should be no difference.
