Webapp failed to execute initialization process which previously worked

I created a pretty simple initialize process that just retrieves a couple of ExampleSets and publishes them. This worked fine and I added a component to display each one.
However when I return to the app the next day, load it up in the editor and try to run the initialization process I get an error message:
"Failed to execute initialization process: Error executing process <path to process>/initialize: null"
The process runs fine in RM Studio and the two app objects that I am expecting are correctly created. It appears to be an issue with the way that RM Server is executing the initialize and retrieving the objects.
I am out of ideas on how to debug this as I can't find anything wrong. Any ideas?

Thanks Rodrigo,
I discovered that trying to run the initialize process for the sample "Model Management" app that ships with RM server causes the same error.
Looking in the server.log shows this error:
15:49:02,820 WARNING [de.rapidanalytics.web.beans.report.ReportController] (http-/0.0.0.0:8080-4) Failed to execute app initialization process for report: '/apps/model-management/app/Model Management App'.

I also have an open case with RM Support on this given that it does not appear to be limited to my own code.
first of all thanks for the report!
We will investigate whats causing the issue and keep you updated.
Cheers,
Marcel
Thanks
