[cross-project-issues-dev] UI tests on HIPP - segfaults and browser support

Hi everybody,

Do any of you have UI tests running on HIPP? I'm running SWTBot tests on the MPC HIPP using Xvnc, and I'm currently having a couple of problems:

1. MPC is using the embedded SWT Browser widget, and since the default XULRunner support doesn't work on GTK3, I moved my tests to WebKit (using -Dorg.eclipse.swt.browser.UseWebKitGTK=true -Dorg.eclipse.swt.browser.DefaultType=WebKit). Now I just get a very nondescript "Internal browser is not available: No more handles" SWT error the first time the browser is initialized, and all my browser-related tests (still) fail.

2. I recently switched my target platform to Oxygen, and now my UI tests always segfault somewhere down the line:

> # A fatal error has been detected by the Java Runtime Environment:
> #
> #  SIGSEGV (0xb) at pc=0x00007f19ea78b510, pid=10922, tid=0x00007f1b077af700
> #
> # JRE version: Java(TM) SE Runtime Environment (8.0_102-b14) (build 1.8.0_102-b14)
> # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.102-b14 mixed mode linux-amd64 compressed oops)
> # Problematic frame:
> # C  [libgdk-3.so.0+0x38510]  gdk_test_simulate_button+0x0

It looks like this happens the first time SWTBot "clicks" on a Link widget. But I don't have the faintest idea what to do about it.

What makes this even more complicated is that I can't reproduce any of this in my own Linux VM. So any ideas how to get this solved would be greatly appreciated.

/cheers
Carsten
