failing test case for ReflectionMethod::getPrototype() when a class is using a trait that defines a method, chich class extends another class that defines the same method too.

gistfile1.php

<?php

trait TestTrait
{
    public function getKernel()
    {
    }
}

class BaseTest
{
    public function getKernel()
    {
    }
}

class Test extends BaseTest
{
    use TestTrait;
}

$refl = new \ReflectionClass('Test');

var_dump($refl->getMethod('getKernel')->getPrototype());

var_dump($refl->getMethod('getKernel')->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype()->getPrototype());
