Reproduce steps:

• created a .bpmn file with the camunda standalone modeler
• closed the modeler
• from the context menu of the file explorer (on the file I created) I picked "open with camunda modeler"

Problem:
An error message shows up: "No document root in resource bundle", but software starts.

Expected behavior:
I wanted the modeler to open the bpmn file without error message

Hints:
After closing all documents who were open in the modeler (including the one who was still open but deleted on the disk) the error message didn't came again.
