Description:
------------
See script.

Test script:
---------------
<?php
class Foo {}
        
class Bar extends Foo { 
        public $var = 'BarVar';
}

class Qux extends Foo {
        private $var = 'QuxVar';
}

$class = new ReflectionClass('Bar');
$prop = $class->getProperty('var');
echo $prop->getValue(new Qux());

Expected result:
----------------
A 'ReflectionException' with message 'Given object is not an instance of the class this property was declared in'.

This would mirror the behavior with methods:

<?php
class Foo {}
        
class Bar extends Foo {
	function foo() {}
}

class Qux extends Foo {
	private function foo() {}
}

$class = new ReflectionClass('Bar');

$meth = $class->getMethod('foo');
$meth->invoke(new Qux());

PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Given object is not an instance of the class this method was declared in'

Actual result:
--------------
PHP Fatal error:  Cannot access private property Qux::$var
