Hi Alexander,

>  530     XkbSetDetectableAutoRepeat((Display *) jlong_to_ptr(display), detectable, NULL);

I suggest to convert the jboolean "detectable" to Bool explicitly to 
avoid any potential compiler warnings. No need for a new webrev with 
this change. The fix looks fine to me otherwise (though I see no point 
in modifying make/sun/xawt/mapfile-vers - the old build is dead.)

Did you run KeyEvent regression tests with your fix (both open and 
closed)? Also, perhaps TextArea/TextEdit tests (from both AWT and Swing) 
might be worth running as well.

best regards,
