This is a duplicate of #317 and has been fixed with https://jira.spring.io/browse/SPR-14444
You should upgrade to spring 4.3.2 / boot 1.4.1.
Please note that you'll get another exception in the logs which is described here: #286 and handeld by https://jira.spring.io/browse/SPR-14739 and will be fixed in spring 4.3.4 / boot 1.4.2

Sometimes this might come when doing deserialization, Use @JSON ignore where were the @onetomany or vice versa used. It resolve this issue.
