무슨오류지...
잘은 몰라도 JRebel 이란 단어가 눈에 띄었고 jackson.databind 란 단어가 눈에 띄었다.
최근에 스프링 4.1 버전으로 업그레이 하면서 함께 버전업을 시켜놓은 녀석들이다.
구글링 해보니 자세한 원인은 파악할 수 없었다.
다만 JRebel 과 jackson-databind와 버전이 맞지 않아서 발생하는 오류인 듯 하다는 내용을 발견했다.
JRebel 6.1.1 버전 까지는 jackson-databind 2.5.5 까지는 오류가 없다고 한다..
JRebel 6.1.2 버전 부터 jackson-databind 2.6.0 버전을 사용해도 된다는 내용이다.
필자는 JRebel 6.0.0 버전에 jackson-databind 2.8.9 버전을 사용중이였다.
JRebel 버전을 올리기에는 모든 직원들의 개발환경에 영향을 미칠 수 있기 때문에
jackson-databind 의 버전을 내리기로 했다.
물론 spring 4.1 에서 MappingJackson2HttpMessageConverter 를 사용한다면 버전을 내림으로 인해 문제가 없는지 살펴봐야 한다.
jackson 라이브러리를 2버전대로 사용한다면 큰 문제는 없을 거라 판단이 되어 2.5.5 버전으로 내렸다.
참고로 연관되어 있는 jackson-annotations, jackson-core 도 jackson-databind 버전에 맞춰서 2.5.5 버전으로 내렸다.
끝.
