[OpenJDK 2D-Dev] [9] RFR JDK-6801613, , Cross-platform pageDialog and printDialog top margin entry broken

[prasanta sadhukhan]

Hi All,

Please review a fix for jdk9
Bug: https://bugs.openjdk.java.net/browse/JDK-6801613
webrev: http://cr.openjdk.java.net/~psadhukhan/6801613/webrev.00/

The issue was the PrinterJob cross-platform "Page setup dialog" top 
margin entry is broken.
  If you enter a value in the top margin field and hit "OK", the value 
is not updated in the PageFormat instance return value,
nor is it updated in the attribute set used to call the pageDialog method.
Tabbing out of the top margin field before hitting OK does not fix the 
problem.
Likewise, clicking on a different margin entry field before hitting OK 
also does not fix the problem.

The reason was we created topMargin JFormattedTextField once and added 
focusListener and ActionListener to this textfield but
we overwrote the topMargin textField again by creating another instance 
and in that instance, we failed to add actionListener or focusListener,
so when we tabbed out of topmargin field, focusLost() method was not 
called which would have called updateMargin() method to update the margins.

Fix was to remove this erroneous instance creation and overwriting of 
topMargin textfield.

Regards
Prasanta
