Hi All,

Please review the fix for JDK12.





     Resizibility of Frame with state MAXIMIZED_BOTH is set to false 
when Frame is resized and when Frame state is set. Resizibility of Frame 
in other states (NORMAL and ICONIFIED) is changed if the previous state 
of the frame was MAXIMIZED_BOTH otherwise it is not changed.

Changes in method setResizable()
  1) if setResizable passed true, then check if frame is in 
MAXIMIZED_BOTH state, if so then set setResizable to false, otherwise 
set to true.
  2) if setResizable passed false, then set false without checking the 
frame MAXIMIZED_BOTH state.

Changes done in method setVisible and setWindowState where Frame state 
is set:
  1) Before setting any state check if resizibility was changed to 
MAXIMIZED_BOTH earlier, if so then set resizibility to false.
  2) When Frame state is set to MAXIMIZED_BOTH then set resizibility to 

JCK and Jtreg (open and close) tests executed with the change:
  1) All automated AWT and Swing tests.
  2) All manual AWT and Swing tests related to Frame, Window, JFrame and
