Ah, I see the Component.getNativeContainer() checks whether the peer is
lightweight or not. I believe it needs to be overridden in the Window
class to return "this", though. Otherwise there's still a bug in this

I don't quite understand this point. Please elaborate.
What I see is that we call SunToolkit.getNativeContainer() which isn't
overridden in UNIXToolkit nor XToolkit, and thus results in a call to
Toolkit.getNativeContainer(). The latter calls
Component.getNativeContainer(). Which, w/o an override suggested above,
produces an incorrect result and is the root cause of our bug, isn't it?
