Pipe exceptions in catch block raise violations

[mamyn0va]

atom version : 1.27.2

linter-php version : 1.5.1

When I lint this PHP 7.1 code in Atom...

try {
  $this->someFunction();
} catch (MyException | \Exception $e) {
  $this->logger->error('Oops');
}

... I get many violations such as Unexpected '|'.

But when I lint from the CMD (php -l), I get no error.

I thought that the linter-php package only calls the PHP linter and then display the output, but obviously this is not what happens.
