Description:
------------
This is a problem in PHP 5.0.0b3 (distro), which wasn't an option in the bug report select list.

Basically, upon upgrading to PHP5.0.0b3 our application generated runtime Reflection_Exceptions claiming to be unable to find the class specified by a class hint.

E.g. when calling

$params = $method->getParameters();
$hint = $params[0]->getClass();

Changing the class hint to lowercase fixes this problem.

Reproduce code:
---------------
class Foo {
}

class Bar {
  function demo(Foo $f) {
    // nothing
  }
}

$class = new Reflection_Class('Bar');
$methods = $class->getMethods();
$params = $methods[0]->getParameters();
$hint = $params[0]->getClass(); 
// reflection_exception was thrown

print "Class expected is: ". $hint . "\n";

Expected result:
----------------
Class expected is: Foo

Actual result:
--------------
<b>Fatal error</b>:  Uncaught exception 'reflection_exception' with message 'Class Foo does not exist' in ...
