Spring Data Rest 2.0.0.RELEASE Breaks Code Working

Question

I have a project which is utllizing Spring Data Rest. I originally had version 2.0.0.BUILD-SNAPSHOT in my pom.xml, but during my last update the code broke and began throwing the following IllegalStateException when accessing most endpoints:

java.lang.IllegalStateException: No suitable resolver for argument [0]
[type=org.springframework.http.converter.HttpMessageNotReadableException]
HandlerMethod details: 
Controller [org.springframework.data.rest.webmvc.RepositoryEntityController]
Method [public org.springframework.http.ResponseEntity<org.springframework.data.rest.webmvc.support.ExceptionMessage> org.springframework.data.rest.webmvc.AbstractRepositoryRestController.handleNotReadable(org.springframework.http.converter.HttpMessageNotReadableException)]

Then the following error is logged by Spring Boot Actuate:

2014-02-28 07:58:54.986 ERROR 9232 --- [nio-8080-exec-6] o.s.b.actuate.web.BasicErrorController : org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: (was java.lang.NullPointerException) (through reference chain: org.springframework.hateoas.Resource["content"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: org.springframework.hateoas.Resource["content"])

If I modify my pom.xml to use SDR version 2.0.0.RC1 then everything seems to work as expected.

I'd like to get this resolved since there are bug fixes included in the latest release which I have been waiting on, but this issue is preventing me from upgrading. Is there a workaround? It's difficult from the stacktrace to even tell where the issue is, but based on timing alone I think this issue may be related to this commit:

https://github.com/spring-projects/spring-data-rest/commit/3e5914d84f9708015b36a8840a25e9fa10a7f6ae

As requested the dependencies are:

spring-data-rest-webmvc 2.0.0.RELEASE

spring-boot-starter-web 1.0.0.BUILD-SNAPSHOT

spring-boot-starter-actuator 1.0.0.BUILD-SNAPSHOT

spring-boot-starter-security 1.0.0.BUILD-SNAPSHOT

spring-boot-starter-data-jpa 1.0.0.BUILD-SNAPSHOT

spring-boot-starter-shell-remote 1.0.0.BUILD-SNAPSHOT

spring-boot-starter-tomcat [provided]

spring-boot-starter-test 1.0.0.BUILD-SNAPSHOT

spring-security-ldap 3.2.0.RELEASE

It appeared that spring-boot-starter-jpa was providing an older version of spring-data-commons than spring-data-rest-webmvc, but reordering the dependencies to pull 1.7.0.RELASE instead of 1.7.0.RC1 doesn't seem to have had an effect.

Answer 1

This is a known and fixed bug basically masking a Jackson serialization problem on our side. The fix is already in and will be in the 2.0.1 release as well as 2.1 M1.

Feel free to give the snapshots a try.
