I am creating a PrintRequestAttributeSet and adding a MediaTray.MANUAL attribute. I am calling PrintServiceLookup.lookupPrintServices() with a GIF DocFlavor and this attribute set. This method returns few printers on SolSparc10-Non CUPS mode.

When I try to print a GIF image using one of the returned printers, I am getting the following exception:
java.lang.NullPointerException
at sun.print.UnixPrintService.getSupportedAttributeValues(UnixPrintService.java:698)
at sun.print.RasterPrinterJob.setAttributes(RasterPrinterJob.java:1151)
at sun.print.RasterPrinterJob.print(RasterPrinterJob.java:1287)
at sun.print.UnixPrintJob.printableJob(UnixPrintJob.java:618)
at sun.print.UnixPrintJob.print(UnixPrintJob.java:382)
at BMPPrintingTest.main(BMPPrintingTest.java:77)

This is not reproducible on Win32, Sol10-CUPS. This is not reproducible on Mustang-b41 with the same testcase. Hence it is a regression introduced in the PIT build.

Here is the PIT build:
java version "1.6.0-2d.pit-awt-blade"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-2d.pit-awt-blade-tdv_20_Jun_2005_00_52-b00)
Java HotSpot(TM) Server VM (build 1.6.0-ea-b41, mixed mode)

First of all, I am surprised to see a 'true' return value from isAttributeValueSupported(MediaTray.MANUAL) when MediaTray attribute category itself is not supported. I should not have got any printers while calling lookupPrintServices() in the first case.

I have attached a sample test. Execute the sample test with the PIT build on SolSparc10-NonCUPS. You would see the above exception.
