<AWT Dev> question regarding test java/awt/PrinterJob/SameService.java (tests that print services are not re-created)

Hello, I have a question regarding   the test  java/awt/PrinterJob/SameService.java  ;  the test deals with    @bug 6446094   .

It checks that  print services   are not re-created  ,   which was  addressed  (or at least discussed )  in   6446094 ,

Win32PrintServiceLookup.getPrintServiceByName() should not recreate duplicate instances.

However  6446094  just  talks about Windows ,  and I see  sporadic   failures on some Linux   test machine  in  java/awt/PrinterJob/SameService.java
  because  the print service is   (seldom)   recreated  on Linux   ( it is even non-deterministic, on the same machine the test  fails in ~ 30 % of runs and succeeds  in the other cases ) .

Can we make the test  Windows-only     ( I think the API does not  guarantee   that  print services   are not re-created   , although it is  desired )   ?

Best regards, Matthias
