title: Why grayed var:colon is added in Java editor in IntelliJ
body: <p>I installed IntelliJ 2016.3.2
  Build #IC-163.10154.41 
  Built on Dec.21, 2016</p>
  
  <p>grayed var:colon is automatically added in front of argument in a caller method in Java editor as you see below ( greyed a: b: are added). 
  Why is this happening? I don't want to see these grayed ones. 
  How to set it up in config.? (I guess this is occurring in the latest version of IntelliJ since I'm using older version in another machine without this problem.)</p>
