Description
FULL PRODUCT VERSION :
1.5.0_11-b03
ADDITIONAL OS VERSION INFORMATION :
Windows
A DESCRIPTION OF THE PROBLEM :
it seems an improper implementation with sun.print.Win32PrintService.getSupportedAttributeValues(line 1203):
if ((isCollateSup && flavor == null) ||
(flavor.equals(DocFlavor.SERVICE_FORMATTED.PAGEABLE) ||
flavor.equals(DocFlavor.SERVICE_FORMATTED.PRINTABLE))) {
The argument "flavor" can be null according the API document, but if "isCollateSup" is false(it is case for the virtual printer "Microsoft Office Document Image Writer"), a NullPointerException will be thrown out for a null DocFlavor.
REPRODUCIBILITY :
This bug can be reproduced always.
