[OpenJDK 2D-Dev] [9] RFR: JDK-8154057, , [macosx] getPrintJob doesn't throw NPE if Frame is null AND type is COMMON

[prasanta sadhukhan]

Hi All,

Please review a fix for jdk9.
Bug: https://bugs.openjdk.java.net/browse/JDK-8154057
webrev: http://cr.openjdk.java.net/~psadhukhan/8154057/webrev.00/

As per spec, Toolkit.getPrintJob() should throw NPE if null frame object 
is passed to it.
But on macos, it seems getPrintJob() does not check for null frame and 
show the print dialog.

Fix is to check for null frame which is same as what we do in windows 
(WToolkit) and linux (XToolkit).

Prasanta
