Ah, I see the Component.getNativeContainer() checks whether the peer

Window class to return "this", though. Otherwise there's still a bug
in this method.
But window's implementation mix owner/container during initialization of
WWindowPeer. There is only one field "parent", which assigned from the
SunToolkit.getNativeContainer().
I assume that, when this method was added the window's parent/container
and the window's owner were one concept.
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?
The question is, what the result is correct. Currently, some code
expects the owner will be refunded.

Hello,
Please review the fix for jdk 8.
SetEnable method check status of all parent containers and windows(via
getParent() in SunToolkit.getNativeContainer()). But only
containers in
the same window should be checked.
The new method was added to return the peer of the nearest heavyweight
container.
