Even I removed lombok, so we should rollback again to Java 1.8?:)

Answer 1

As I understand we need add following Java OPTs params:

 - JVM_OPTS=  --add-exports=java.naming/com.sun.jndi.ldap=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.security=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.management/javax.management=ALL-UNNAMED --add-opens=java.naming/javax.naming=ALL-UNNAMED

for example I added in docker compose.

I think soon Spring boot/JakartaEE will upgrade their configurations.

Answer 2

Have same issue. Don't use gson mapper. Remove next line from application.properties file.

spring.mvc.converters.preferred-json-mapper=gson

Answer 3

I excluded gson the first and added mapper:

@Configuration
public class JacksonOffsetDateTimeMapper {

    @Primary
    @Bean
    public ObjectMapper objectMapper() {

        ObjectMapper mapper = new ObjectMapper();
        mapper.registerModule(new JavaTimeModule());
        mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
        SimpleModule simpleModule = new SimpleModule();

        mapper.registerModule(simpleModule);
        return mapper;
    }
}
