I just found out that if I comment out the line:
$_SERVER = new \F3\FLOW3\Utility\SuperGlobalReplacement('_SERVER', 'Please use the ' . __CLASS__ . ' object instead of accessing the superglobal directly.');

The $this->SERVER variable is available in the child class of F3\FLOW3\Utility\Environment.
Is that a intended behavior?
