Run a regression test closed/java/awt/Cursor/BlockedWindowTest/BlockedWindowTest.
It does set a hand cursor over a part of the frame and also does display a text cursor over a text field. Then, a tester does fire a modal dialog. According to the test presumption -- see also a discussion in 6391547 -- a cursor all over the blocked frame should be default one. 
However, all components in the blocked frame still change their cursors.
Also, the blocked Frame blinks uncomfortably when clicked on, together with the blocking Dialog. If that last fact is worth a CR please fill one!
