RFR for JDK-8027901 Intermittent test failure java/net/ProxySelector/MultiThreadedSystemProxies.java

[Chris Hegarty]

Charlie,

When I run this test with DISPLAY unset, or set to <empty string>, and 
on a system without the latest Gnome 3 libraries ( more specifically NOT 
having libgio-2.0.so ), I get a warning that GConf cannot be initialized 
(see below). I do not see this test hanging.

---
(process:25718): GConf-WARNING **: Client failed to connect to the D-BUS 
daemon:
//bin/dbus-launch terminated abnormally with the following error: 
Autolaunch error: X11 initialization failed.

GConf Error: No D-BUS daemon running
---

To summarize, the problem here is that DISPLAY needs to be set on the 
test system to be able to initialize GConf. Once the DISPLAY is set then 
the test passes fine. I don't see any issue here. I think we can closing 
this bug as 'not a bug', it is a test machine configuration issue.

Also, more recent Linux versions with Gnome 3 support do not need 
DISPLAY to be set to initialize.

-Chris.
