Nie można odczytać JSON: Nie można przekształcić do postaci szeregowej instancji org.springframework.xd.rest.domain.JobExecutionInfoResource [] z tokenu START_OBJECT - spring-xd

Uzyskanie tego błędu podczas uruchamiania poniżej kodu w eclispe

SpringXDTemplate xdTemplate = new SpringXDTemplate(new URI("http://my.ip:9393"));
List<JobExecutionInfoResource> listJobExecutions = xdTemplate.jobOperations().listJobExecutions();

używam spring-xd version 1.3.1, a poniżej jest stacktrace błędu:

Właściwie to był problem ze słoikami.W kodzie używałem słoju SP4 dla klientów spoczynkowych, a moja wersja xd wiosna była w wersji 1.3.1. Ponadto najnowszy słoik-klient (1.3.1) nie jest dostępny w maven, ale to samo jest dostępne w folderze wdrażania spring-xd.
