AFAIK you should not use String for ApplicationsStateObjects nor other primitive types at all .. only complex types with a no arg constructor. if you must use a different constructor you have to contribute to the ApplicationStateManager to tell the service how to create the instances properly

If I understand well, I have to create a custom ApplicationStateContribution to handle ApplicationState on String class ? Do you have some tips or instructions to do this ? I will try and tell you the result. I am just surprised that this configurations was working well before 5.0.11 version ...
