As of ORM 5.0.7 ( HHH-9474 - Perfomance issue with ElementCollection Complete ), ORM will avoid the recreation of element collections with an index column when updating their contents.

This revealed an issue in Neo4jDialect#putAssociationOperation() where we'd forget to apply property updates on the embeddable in the case the relationship exists already (before, it would always be removed and re-created).
