Hey! I've spotted you'r bug report on JIRA
https://jira.spring.io/projects/DATAJPA/issues/DATAJPA-1428?filter=allopenissues
Don't have acc there, so i'm, writing here. So, there is no bug in data JPA. This recursive loop is caused by
@ Data lombok annotation. How?
You have an entity which has another entity. When you're using @ Data it's generating by default hashCode method, which is necessary for equals. And default hashCode are hashing not only primitives values but other fields too. So in Role entity this method hash associated Privilege, then hash this Privillege which - has Role. And there is beggining of infinite loop.
