Re: 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.

Hi,

it seems that 

 if (cs.equals(this))
  return true;

should be replaced with

 if (cs instanceof String)
  return cs.equals(this);

or completely left out.

Does anyone agree?
