Will a carriage return be correct or not for the PSR-2?

Question

I use to create my classes like this, with an extra blank line after the closing } (here line 9):

<?php
class myClassName
{
    public function index()
    {
        // my code here
    }
}
// here

This helps me to find the functions list when I use my favorite coding tool, notepad++ but i've heard that it can be an error on some PSR validators. Reading the PSR-2 coding style guide, I don't find anything about this one.

Does this cause errors in validators?
