Could you please review the following fix for the bug.

Bug: https://bugs.openjdk.java.net/browse/JDK-8167102
Webrev: http://cr.openjdk.java.net/~alitvinov/8167102/jdk9/webrev.00

The bug consists in the fact that, if the user's application specifies 
the required page size (media size) through "java.awt.print.PrinterJob" 
API particularly via "java.awt.print.PageFormat" instance supplied to 
the method "PrinterJob.setPrintable(Printable, PageFormat)" and calls 
"PrinterJob.print(PrintRequestAttributeSet)" with 
"javax.print.attribute.PrintRequestAttributeSet" containing at least 1 
any "PrintRequestAttribute", then the page or pages will be printed with 
"PageFormat" describing the default page size of the printer which is 
different from the expected and originally set by the user's application 

Debugging showed that the new "PageFormat" with unexpected media size is 
created in the method 
"sun.print.RasterPrinterJob.getPageFormatFromAttributes()" which is 
invoked from the native function 
The method "RasterPrinterJob.getPageFormatFromAttributes()" returns a 
new "PageFormat" always, if the provided by the user 
"PrintRequestAttributeSet" is not empty, and the default values are set 
to particular instance variables of this "PageFormat", if 
"PrintRequestAttributeSet" does not contain the searched 
"OrientationRequested", "MediaSizeName", "MediaPrintableArea" attributes.

Although it is clearly stated in Java Platform SE 8 API Specification 
(documentation of the method "PrinterJob.print(PrintRequestAttributeSet)")
Specification URL: 

that media size, orientation and imageable area attributes specified in 
"PrintRequestAttributeSet" supplied to the method "PrinterJob.print" 
will be used for construction of a new "PageFormat", which will be 
passed to "Printable" object, instead of the original "PageFormat" 
instance set through "PrinterJob.setPrintable" method, the observed in 
this issue behavior is a bug, because in the bug test case neither media 
size, nor orientation, nor imageable area attributes are specified in 

The fix alters the method 
"sun.print.RasterPrinterJob.getPageFormatFromAttributes()" to use 
corresponding values from "PageFormat" instance originally set through 
"PrinterJob" API during construction of the new "PageFormat", when it is 
found out that "OrientationRequested", or "MediaSizeName", or 
"MediaPrintableArea" attribute is not specified in 
"PrintRequestAttributeSet" supplied to "PrinterJob.print" method.

Thank you,
