This community does not provide technical support and is not staffed with technical support experts. I recommend you post this and future technical support questions to the Cisco Support Community (https://supportforums.cisco.com/index.jspa) where our Cisco technical support experts provide debugging assistance or to Cisco Webex Support for help 24/7 (Support Tools and Resources | WebEx).

We do encourage you to participate in the Cisco Collaboration Community and to also join our Cisco Collaboration User Group program! In the community, we encourage your discussion/sharing around collaboration topics and Cisco Collaboration Solutions, including business and IT requirements, industry trends, process, culture/organization issues, how collaboration can be used to transform businesses, vendor selection, adoption, training, architecture, licensing, and product features/functionality. If you are a customer or partner, you can also join the user group program to be eligible for member-only events and influence product direction.

We hope to hear from you again

Hello Csaba.

I've also suffering from this bug. Unfortunately, webex support is worse than bad. The only answer I've got is that Ubuntu 14.04 is not supported.

Happily I've found a way to launch webex session. When Java ask whether to block or no webex applet, I've pressed "Block" my mistake. Unexpectedly, the stack trace no longer appears and the webex session starts up.

I expect this to be useful.
