Description:
------------
I wanted to instantiate a object of the class ArrayList but did not define a "use ...\ArrayList" and everything hung up. No response was send from the server, neither a error message nor an empty page.

Test script:
---------------
namespace test;
class A{
public function __construct(){
$arr = new ArrayList();
}
}

-----
namespace test2;
class ArrayList{...}

-----
namespace test3;
$class = new ReflectionClass('A');
$aObj = $class->newInstance(null);

Expected result:
----------------
Error, test3\ArrayList was not found

Actual result:
--------------
Endless loop
