Looking at this again, while the text of ICCCM section 4.1.7 is pretty opaque,
the implementation actually seems to be quite straightforward.

I've added a patch which makes input focus handling more closely follow ICCCM,
and generates the WM_TAKE_FOCUS message when needed.

I've tested this very briefly with the TypeInSwing.java test case in sun bug
#6798064 and the jdk Notepad demo.

I've uploaded a snapshot at [1]. Perhaps you could try that and see if it
improves things for you?
