Hi Anton,
Not sure if this matters much, but normally we don't use *.swing.*
classes directly from *.awt.* classes to avoid inter-dependencies. It
would look better if you could use an approach based on the
Class.getName()/Class.getSuperClass() methods here.
Also, I don't quite understand why "in case of interop WM_PAINT is never
triggered". W/o understanding this, I'm not sure if the current fix is
correct. Please elaborate on the root cause of the bug.
