So there still are these failures in the examples tests and physmon tests... It looks like something does not work here with the access of the stored objects I think, but currently fixing this is not my priority. I'll leave the PR open for now, so if someone has an idea whats going on here we can proceed on this.

what was the problem with these changes @benjaminhuth ? I might want to follow up on this later
