org.sintef.thingml.resource.thingml.ui was unable to load class org.sintef.thingml.resource.thingml.ui.launch.ThingmlLaunchShortcut.

I have the Kevoree helloworld Java project in my workspace and was working on this project.
Only a second project is in the workspace: ThingML_Basics (from the first training).

Then I get the following issue in the Eclipse error log.
I've no clue what caused this.

We'll look into that. Is that crashing the whole Eclipse or can you still work on the Kevoree tutorial

[skorsky]

It is not crashing Eclipse. I can still work on the tutorial.

Saw this exception again. Somehow related to the Debug UI. Copy of the error log entry below.

I guess this is fixed. If not, re-open
