When trying to denormalize an object (from JSON, but this is not relevant) using the "constructor way", the parameter order can be incorrect under certain conditions.

For example if I use a constructor like this

public function __construct($foo, $bar = array(), $baz = array())

and use the following data for denormalization

array('foo' => 'test', 'baz' => array(1, 2, 3))

I'd expect the constructor to be called like this

new MyClass('test', array(), array(1, 2, 3))

but this is what happens in reality

new MyClass('test', array(1, 2, 3))

so the value that is "baz" is used for "bar", which is really unpleasant.

I'm only starting my "life with Symfony" and don't have the time to read on the docs and make a proper pull request now, so I hope anybody else could do that. This bug is present ever since Symphony 2.0.
