util.inspect behaves differently on different node versions

code:

var util = require('util')
var body = '{doc}'
try{
  body = JSON.parse(body)
}catch(err){
  console.log(util.inspect(err))
}

The same code running on different versions giving different results

node 6.x.x: (inspect is not working)

SyntaxError: Unexpected token i in JSON at position 1
    at Object.parse (native)

on node 0.x.x:

[SyntaxError: Unexpected token i]

PS: I have used depth null, still am getting same results on nodev6
