Hi Phil,
Bug: https://bugs.openjdk.java.net/browse/JDK-8058316
webrev: http://cr.openjdk.java.net/~psadhukhan/8058316/webrev.00/
The issue was on some Solaris 11 hosts lookupDefaultPrintService()
returns null while lpstat -d reports an ipp printer.
The issue was found to exist in linux too since it uses CUPS.
What was happening was that CUPSPrinter.java#getDefaultPrinter()
searches for server-defined default destination by connection to CUPS
server but
if the user sets the default printer using "lpoptions -d <printername>"
command, server will not have any knowledge of this settings and this
user-set default printer (which is stored in ~/.cups/lpoptions file) was
not searched
and getDefaultPrinter() returns null since it could not find any server
default printer.
Fix is to call cupsGetDest API to search for a lpoptions-defined default
printer and if not set, then search for server-defined destination.
I could not provide a regression testcase for this as it involves
setting default printer using lpoptions command.

Prasanta
