Exception with JaVaDe8 after creating a project

Hi!

Thank you for this great Vaadin addon. I really like it and prefer JaVaDe even to the official WYSIWYG editor, because it generates Java files only and not the declarative html files...

At the moment I cannot get JaVaDe8 to run on Wildfly 10. I had JaVaDe running on Wildfly 10 for a long time, but after an update to JaVaDe8 the application throws an exception after I created a project. After installation and starting the application I can see the UI and create a new project, but after creating the project I cannot continue, because of this exception.

Here is the stacktrace:
