Found cycle for field Spring Mongo Data 1.8.2

I'm writing a UnitTest for my app and I have de wierd bug. My app is working well but when I'm lauching my test I have the following message :

[mongod output] 2016-01-22 12:30:37,078 INFO DEMO [NO_USER] {main} o.s.d.m.c.i.MongoPersistentEntityIndexResolver[doWithPersistentProperty:267] - Found cycle for field 'defaultAddress' in type 'Contact' for path 'customers.contact' org.springframework.data.mongodb.core.index.MongoPersistentEntityIndexResolver$CyclicPropertyReferenceException: Found cycle for field 'defaultAddress' in type 'Contact' for path 'customers.contact'

It seems like @JsonIgnore annotation is ignored. I tried to put it on the property and on the getter but no changes. This message never stops looping.

Any Ideas ?
