Building reflection cache in ClassSchema on static class properties will
lead to side-effects. For instance when ConnectionPool is analyzed for
being used with Extbase dependency injection and has been used already
during runtime - which is very likely - static property $connections is
going to hold all runtime connections.

https://www.php.net/manual/en/reflectionclass.getdefaultproperties.php:
> This method only works for static properties when used on internal
> classes. The default value of a static class property can not be
> tracked when using this method on user defined classes.

That's why default values of static properties are not resolved anymore.
