> This change resolves the issue that drag and drop from a Java application to a native Wayland application (such as gedit) is not possible on Linux.
> 
> Our code it quite picky for the drop target, and requires it to be a top level window with the WM_STATE property set, whereas the XWayland server provides dummy windows without this property.
> So now we make an exclusion for this case.
> 
> After the fix it successfully passes previously failed related manual jtreg/conformance tests on Wayland.
> Other tests are also passed.
