Neo4J Spring Data - Error adding element with #RelatedToVia relationship to index __rel_types__ using SpringCypherRestGraphDatabase - spring-data-neo4j

Question

I'm working on Neo4j Spring Data project and have started using a "RelationshipEntity" and the "#RelatedToVia" relationship to better model some relationships.
The problem I'm having is if I run an embedded database everything is fine but when I run with a SpringCypherRestGraphDatabase I keep getting the error "Error adding element... to index __rel_types__":
Any pointers would be great!!
Stacktrace:
Caused by: java.lang.RuntimeException: Error adding element 52 className AlsoKnownAs to index __rel_types__

Edited
I can see the same issue was happening on an old Spring Data build:
https://build.spring.io/browse/SPRINGDATA-NIGHTLY-JOB1-697/test/case/92176623;jsessionid=5EE45702C67548804FEF985C00F5DAD2
Still investigating what might have caused that.

Answer 1

Still can't figure a way to fix this issue cleanly.
My only workaround so far was to replace
org.springframework.data.neo4j.rest.SpringCypherRestGraphDatabase
by the now deprecated
org.springframework.data.neo4j.rest.SpringRestGraphDatabase
I am now able to save #RelatedToVia relationships.

Answer 2

I'm having the exact same problem here.
I use spring-data-neo4j 3.3.0.RELEASE and spring-data-neo4j-rest 3.3.0.RELEASE, i had also to add manually spring-data-commons 1.10 (https://jira.spring.io/browse/DATAGRAPH-635)
Using the deprecated class solved the issue, but i'm not sure on my configuration since Michael Hunger said (here http://java.dzone.com/articles/spring-data-neo4j-330) to use the SpringCypherRestGraphDatabase....
