How can I fix Eclipse/RTC 4.0.6 crashes on startup?

Eric Marsh (154) | asked Jul 29 '15, 11:19 a.m.
I've installed RTC Jazz 4.0.6 on two different Ubuntu 14.04 VMs. One of the VMs is from a virgin Ubuntu iso download. The other is from a pre-configured IBM Open Client iso.

The Ubuntu instance starts and runs fine. The Open Client instance crashes on startup.

The top of the stack from the core file looks like this:

I infer that the problem is occurring when it tries to bring of Firefox. I've done some web searches which instructed that the following changes to the environment be made, which I have done.

export MOZILLA_FIVE_HOME=/usr/lib/firefox

Can anyone give me any pointers on how to best attack this problem?

The environment variables are not the "be all" solution, and you need to know why the variables are set in such a way.

Your RTC Eclipse client crashed when trying to load WebKit, not Firefox. You can add the following line to eclipse.ini to force it to load Firefox instead.
If you have not done so, take a look at this old post where many suggestions were made.

If you still have problems, give more details about the issue, such as the complete Java dump (you omitted the top part), the location of Mozilla Firefox (you need to verify its existence), and the eclipse.ini content (if modified).

Thanks, that seems to have solved the problem.
