Description:
------------
The reflection extension does not allow obtaining ReflectionProperty objects for non existent properties, much less fetch their non existent value. However, this can be bypassed by creating a dynamic ReflectionProperty in another object.

Test script:
---------------
<?php
class A {}

$a = new A;
$a->foo = "dynamic property";
$ro = new ReflectionObject($a);
$prop = $ro->getProperty('foo');
try {
	var_dump($prop->getValue($a));
	var_dump($prop->getValue(new A));
} catch (ReflectionException $ex) {
	echo "Caught!\n";
	try {
		var_dump($prop->getValue(new A));
	} catch (ReflectionException $ex) {
		var_dump($ex->getMessage());
	}
}

Expected result:
----------------
string(16) "dynamic property"
Caught!
string(49) "Dynamic property does not exist in given instance"

Actual result:
--------------
string(16) "dynamic property"
NULL
