Oracle BugId: 560041

According to the documentation for Window.getFocusOwner(), it should return
the "child component of this Window which has focus if and only if this
Window is active." However, it always returns the child component the the
Window, regardless of whether the window is active or not.
To reproduce:
  Compile and run the testcase using the appletviewer. It will bring up two
windows. Pressing the button in either window will tell you the focus owner
for the other window. It should return null since the other window will be
inactive, but it doesn't.
