[OpenJDK 2D-Dev] [9] RFR JDK-6509729: javax.print.ServiceUI.printDialog Border/Margin Evaluation is bugged

[prasanta sadhukhan]

Hi All,

Please review a fix for jdk9 whereby it is seen that the pagedialog 
margin validation is incorrect.

Bug: https://bugs.openjdk.java.net/browse/JDK-6509729
webrev: http://cr.openjdk.java.net/~psadhukhan/6509729/webrev.00/

It is seen that if we modify right margin to invalid value like 0,0 and
refocus to trigger validation, right margin remains invalid. Similarly, 
for bottom margin.

This is because validateMargin() in ServiceDialog.java does not check 
for bottom and right margin unlike top,left margin so these margins are 
not validated to correct value.
top/left margin changes back to valid 1.0 value when validateMargin() 
finds the margins invalid but right/bottom does not change the value and 
remains invalid.

Added the right and bottom margin invalid check in validateMargin().

Regards
Prasanta
