The relation between AbstractDocument and Map is containment, right?
Yep, at least that is the symbol for "inner class" relation ship: It reads something like this "AbstractDocument has the inner class Map" but why it is there i have no idea. Thats why we need reviews. I thought i fixed an issue like that some time ago, maybe it creeped back up again. I'll have to look into that, yes.
This issue was put to the side again and i forgot about it :innocent: i will continue work to at least a state that is reviewable locally.
