I have modified the .printers file on my home directory in such a way that there is no '_default' entry in it. All it has is the '_all' entry. On Solaris, lpstat -d returns 'No System Default Destination'. lpstat -v returns all the network printers. When querying the available printers through PrintServiceLookup.lookupPrintServices(), I am getting a printer entry - 'destination'. Actually no such printer is available and lpstat -v does not report this printer. I feel this is taken from the string returned by 'lpstat -d'. On some systems, lpstat -d returns null and hence there is a 'null' printer returned by LookupPrintServices method. This is shown even in the print dialog also as the default printer. This occurs only on the PIT build on Solaris9 without CUPS. On the previous build, this throws an IllegalArgumentException. Here is the PIT build:
java version "2d.pit-jcg-sparc-01-2004-03-31.tiger"
Java(TM) 2 Runtime Environment, Standard Edition (build 2d.pit-jcg-sparc-01-2004-03-31.tiger)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b45, mixed mode)

I have attached a sample code. Execute the sample code. Click on the 'Merlin PrintService Dialog' button shown on the frame. A print dialog will popup. You will see either 'null' or 'destination' as the default printer on the printer combo box. I am printing all the printers returned by lookupPrintServices() on the console. if you find the above mentioned invalid printer in the list, the bug is reproduced. No non-existent printers must be reported by lookupPrintServices method. I could not print anything using this default printer as it throws a PrintException always.

Here is the setup information:

This is seen on 1.4.1 and 1.4.2 but it is not reproducible on any of the tiger builds except the PIT build specified above. Hence this is a regression introduced in the above PIT build.
