Bean failiing to initialize in a not deterministic way

Question

I have a Spring Boot application that has the following bean:

@Configuration
public class ConfigStatus {

    @Value("${olt.id}")
    private int olt_id;

    @Bean
    Status createStatus() {
        return new Status(olt_id);
    }
}

I launch several containers with this application (20 to be exact) and in some of them the bean fails to be initialized and I don't understand why. The bean is successfuly initialized consistently in 18 of 20 containers. Memory is not an issued as the system I am using has 125gb of ram and at the time of this issue is has 90gb of free memory.

This is the class that makes use of the bean:

@DependsOn("createStatus")
@Service
public class ReceiveMessageHandler {

    Logger log = LoggerFactory.getLogger(this.getClass().getName());
    private static final Gson converter = new Gson();

    @Autowired private Status currentStatus;

    public void handleMessage(String body) {
        OltRequest request = converter.fromJson(body, OltRequest.class);
        request.setStartedBeingProcessedAtOlt(new Date().getTime());
        Response r = new Response(request.getId(), 200, new Date().getTime());
        r.setRequestEnqueuedAtOlt(currentStatus.getEnqueuedAtWorkerTimes().get(request.getId())); // line that fails due to the bean being equal to null
        r.setRequestDequeuedAtOlt(new Date().getTime());
        log.info("Processing request: " + request.getId());
        try {
            Thread.sleep(request.getDuration());
        } catch(InterruptedException e) {
            e.printStackTrace();
        }
        request.setEndedBeingProcessedAtOlt(new Date().getTime());
        log.info("Finished processing request: " + request.getId());
        r.setEndedHandling(new Date().getTime());
        Worker.send_response(r, request.getOriginMessage().getWorker());
    }
}

The error messages sais that when the bean was accessed it was null.

In the environment I have another Spring Boot app with 30 running docker containers in which this problem does not occurr, ence my disbelief :D.

Answer 1

All it required json_decode , exactly as below .

$comments = json_decode($request->cashoutexpenses, true);

Earlier i was using only json_decode along with one parameter without true keyword which was not working
