Looking for alternatives to Jackson > 2.x serialization

[atrauzzi]

Encountered a scenario where a dev is customizing Dapr's ObjectMapper by extending DefaultObjectSerializer and modifying the static OBJECT_MAPPER:

static {
  OBJECT_MAPPER.findAndRegisterModules();
  OBJECT_MAPPER.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
  OBJECT_MAPPER.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS);
}

This will break with Jackson 3.x because ObjectMapper/JsonMapper is now fully immutable - configuration must happen at construction time via builder pattern. Methods like disable(), enable(), configure() no longer exist on the mapper instance.

Is there an alternative available for people who have made this kind of customization?

@atrauzzi hey.. thanks so much for reaching out,
is this related to Spring Boot 4? Because Jackson 3 was going to be the baseline for Spring Boot 4, I am checking because I am currently working on supporting Spring Boot 4 and it will help me a lot to see your use case.
