[8u] 8200313: java/awt/Gtk/GtkVersionTest/GtkVersionTest.java fails

[Zhengyu Gu]

Hi,

I would like to backport this patch to 8u, as it is in Oracle's 8u261.

The original patch does not applies cleanly, the only conflict is the 
bug id line.

Original bug: https://bugs.openjdk.java.net/browse/JDK-8200313
Original patch: http://hg.openjdk.java.net/jdk/client/rev/a4a0d0ece022


8u webrev: http://cr.openjdk.java.net/~zgu/JDK-8200313_8u/webrev.00/

Test:
   Tested on Linux x86_64.

Thanks,

-Zhengyu
