Also please checkout Quarkus ( https://quarkus.io/ ) , as we worked closely together to improve bootstrap times - we’re not using Java Serialization but I believe it’s a better approach, as it allows bootstrap in the order of milliseconds when compiled to native image, and it does great in not-native as well. I’m skeptical that an approach based on serialization would be able to outperform the Quarkus boostrap code - not to mention that it would have some problems, such as needing to verify if the serialized state is matching the current application state.
