FULL PRODUCT VERSION :
build 1.6.0_12-b04

ADDITIONAL OS VERSION INFORMATION :
Windows XP, 32 bit

A DESCRIPTION OF THE PROBLEM :
While my Java application is running, if the user adds a new printer via Windows print settings, PrintServiceLookup.lookupPrintServices does not return that printer. This is even worse if the user makes the new printer the default-- our code tries to initially select the default printer.

This appears to be the same issue as 4744405, but supposedly that was not an issue on Windows (and has been fixed on other platforms).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Run the sample code below
2) Click on the button to bring up the print dialog. Press Cancel to close it.
3) While the process is still active, add a new printer via Windows print setup and make it the default printer.
4) Click on the button again to reopen the print dialog.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The print dialog should open with the newly added printer as the selected printer.
ACTUAL -
Exception prints. PrintServiceLookup.lookupDefaultPrintService() returns the new printer, but it is not present in the list of all available printers.

ERROR MESSAGES/STACK TRACES THAT OCCUR :

Not reproducible in 6u10, 6u13, and above. Asked submitter for more info regarding printer trying to add and number of printers installed. Will re-open if I get any new info and can reproduce the same problem.
