> The solution can be to catch "InvalidProtocolBufferException", show warning
> and remove application's folder that contains invalid data to prevent RM
> restart failure.
> Additionally, I've added catch for other exceptions that can appear during
> recovering of the specific application, to avoid RM failure even if the only
> one application's state can't be loaded.
