I've downloaded Carrot2 Document Clustering Workbench for 64-bit Linux version 3.9.4 and tried to run it on my Ubuntu GNU/Linux 14.04.
First I've received an error:
org.eclipse.swt.SWTError: No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]
Then I've installed the following, hoping to fix the error above:
sudo apt-get install libwebkitgtk-1.0-0
Then I tried to run the workbench again but this time I've received:
$ carrot2-workbench-3.9.4/carrot2-workbench

And it got stack on the start-up screen, waiting forever.
Any ideas how I can fix this and run the workbench?
Apparently this is about http://issues.carrot2.org/browse/CARROT-1058 (underlying framework's bug). According to core developers, the options are limited to running the Carrot2 Workbench in a virtual machine with an older Ubuntu (or on Windows / MacOS).
