[OpenJDK 2D-Dev] [9]: RFR JDK-8058316, , lookupDefaultPrintService returns null on Solaris 11

[Yuri Nesterenko]

Thank you, Prasanta!

Could you please add this or similar explanation to that
JDK-8058316? Please use all the words/phrases a desperate
tester would search.
If we cannot have a regression test we should
have enough search terms to find this bug in case of
(apparent) regression.
