Hi Rayner,
This looks like a bug in OMNeT++, since there are classes in the org.omnetpp package on the stack (ResultFileManager, ScaveEditor, EditAction, etc.).
However, there's a chance that it is already fixed internally OR it will never be fixed, because we are in the process of a significant overhaul regarding result processing and analysis using the IDE. András talked about this on the
Community Summit just a few days ago, see the slides for his presentation here:
https://summit.omnetpp.org/2017/assets/pdf/OMNET-2017-Session_4-03-Presentation.pdfIf you're interested, I would also recommend checking out the
draft for a new tutorial in this topic, linked on slide 14.
Thank you for reporting!
Attila
