Activiti Plugin v5.18 Eclipse Oxygen error with diagrams

[rgrazini]

I'm having troubles to use the Activiti Editor with the plugin on Eclipse Oxygen 3.7.1 installed on Ubuntu 17.10 (Artful).

When creating a new diagram this is how it looks when i open it with the Activiti editor

I tried installing others versions of Eclipse but the same thing happens

Here is a snap of the logs on the IDE

After restarting Eclipse with the same workspace it won't open saying that an error ocurred.
Deleting the project directory will work for opening the IDE again

The logs for the errors are attached.

Hi Rodrigo, 

As far as I know the eclipse plugin is not being updated anymore, we are working on new tools for that. In the meantime you should be able to use any BPMN editor, even the one provided in the Activiti WAR App to model your business processes. 

Alternatively you can use an old version of Eclipse that will probably work with the plugin.
