    I think catching the `ClassCastException` is not the proper way to fix this. This might
be masking other (real) bugs that lead to `ClassCastExceptions`. We should detect whether
the wrong type is used for accessing a state that was already registered in the part of the
code that does this, probably in `AbstractKeyedStateBackend`.
