On my 32-bit Ubuntu 12.04 LTS I have RTC 4.0 client (unpacked from a plain zip). It functioned normally until at some point I tried to click on a "History" tab. Then I get errors like below:

Error logged from Process Client UI: 
No more handles [MOZILLA_FIVE_HOME='/usr/lib/xulrunner-addons'] (java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
/home/dubauski/dev/jazz/client/eclipse/configuration/org.eclipse.osgi/bundles/502/1/.cp/ ( cannot open shared object file: No such file or directory)
swt-mozilla-gtk (Not found in java.library.path)
/tmp/swtlib-32/ ( cannot open shared object file: No such file or directory)
/tmp/swtlib-32/ (/tmp/swtlib-32/ cannot open shared object file: No such file or directory)
After this error I'm recommended to exit RTC workbench.

I have searched extensively on this issue and have tried to switch to a different xulrunner (,,, 3.6.28, 16.0.2, etc) but to no success. At best I was getting different errors or RTC would simply crash.

I specify an installation of xulrunner to use with the instructions on the Eclipse SWT FAQ. I use the first option with the -D flag to set the xulrunner location.

Then I use one of the versions that is supported based on the Eclipse version I'm using as specified here.

For RTC 4.0, it is using Eclipse 3.6.2 and the 1.9.x versions of xulrunner should work. It seems to be looking in /usr/lib/xulrunner-addons for your xulrunner. Is this the correct location where you've installed xulrunner?

Thank you Tim! The combination of -D flag option in eclipse.ini with xulrunner v. worked.

To those who has the same problem with RTC 4.0 on Ubuntu 12.04 and would like to know the exact steps here they are:

1. Install xulrunner v. by running script below (borrowed from

FFVER= ARCH=uname -p 


cd /opt 

sudo sh -c "wget -O- $XURL | tar -xj" 

sudo ln -s /opt/xulrunner/xulrunner /usr/bin/xulrunner 

sudo ln -s /opt/xulrunner/xpcshell /usr/bin/xpcshell

2. Modify RTC's eclipse.ini file by adding the following -vmargs parameter:

Perfectly summed up. Thanks.

That's great, it solved the problem I always had with my RTC (whatever version) Eclipse client on Ubuntu.

I recently installed RMC( method composer) and encountered the same problem. Following the steps lead to the xulrunner version that's too new and cause XCOMP error. It is recommend to keep using V1.9.2.x if you encounter some other problems.
