How to fix HTML-GUI Error
Daniel Paul-Gattringer
i have got an issue with the html-gui of saros. I am using ubuntu 18.04 with java 1.7.0_80 and Eclipse 3.7.2. I have uncommented the view in plugin.xml and set "saros.swtbrowser = true" in saros.properties as mentioned here: http://www.saros-project.org/html-gui#activating-the-html-gui .
If i run the plugin i get the attached error and the following error message is shown in the console:
ERROR 16:25:08,071 [main] (SarosViewBrowserVersion.java:59) Could not instantiate Browser:

I have installed the libwebkitgtk-1.0.0 which was declared as a posible solution.
Did anyone has the same issues or any idea to solve this?
Kind regards,
Daniel
Zieris, Franz
that's frustrating:
I saw this exact same stacktrace two years ago on a Debian 8 (jessie) 64-Bit with Gnome.
(I know this because I sent it to myself via e-mail.)
Unfortunately, I cannot find a documentation of the steps of how it was fixed on the respective machine back then,
but I'm positive that it was fixable.
As of now, I'm afraid I'm not of much help.

By the way: The error message is gold!
"Saros couldn't initzialisieren the SWT browser widget"
Could someone please provide a patch for this [1]? Thanks!
