Description:
------------
Calling getMethod() on a ReflectionClass object for the current object lowercases the contents of the variable that is passed to it.

Hardcoding the getMethod() parameter prevents the lowercasing while copying the value from $this->name to $name and passing that to getMethod() does not.

Reproduce code:
---------------
<?php
class Foo {
    private $name = 'testBar';
 
    public function testBar() {
        try {
           $class  = new ReflectionClass($this);
           var_dump($this);
           $method = $class->getMethod($this->name);
           var_dump($this);
        }
 
        catch (Exception $e) {}
    }
}

$foo = new Foo;
$foo->testBar();
?>


Expected result:
----------------
object(Foo)#1 (1) {
  ["name:private"]=>
  string(7) "testBar"
}
object(Foo)#1 (1) {
  ["name:private"]=>
  string(7) "testBar"
}

Actual result:
--------------
object(Foo)#1 (1) {
  ["name:private"]=>
  string(7) "testBar"
}
object(Foo)#1 (1) {
  ["name:private"]=>
  string(7) "testbar"
}
