[Neo4j] Neo4j-spring-data(4.1.1) self relationship (parent-child) is duplicated

[pulkit mehra]

I am using spring-data-4.1.1 & Neo4j 2.3.2 with ogm annotations

Below is my entity

        @NodeEntity(label = "Component")
        public class Component extends BaseEntity {
        .........
        
          @Relationship(type = Relation.LINK_TO)
          private Set<Link> links = new HashSet<>();
        
          @Relationship(type = Relation.PARENT)
          private Set<Component> parents = new HashSet<>();
        .........
        .........
        
        
    }

And Link class

    @RelationshipEntity(type = Relation.LINK_TO)
    public class Link extends BaseEntity {
    
        @Property(name = "isSelfLink")
        private boolean isSelfLink;
    
        @StartNode
        private Component component;
    
        @EndNode
        private Component linkComponent;
    }

I've removed getter/setter/hashcode/equals for keeping it clean

Now, here is my code to add two component parent/child and a Link

    Component parentcomp = new Component(1, name);
    Component childcomp =  new Component(2, name);
    childcomp.getParents().add(parent);
    
    Link link = new Link();
    link.setComponent(parentcomp);
    link.setLinkComponent(childcomp);
    parentcomp.getLinks().add(link);
        
    componentRepository.save(parentcomp,-1);


Now, as per the logic

 1. object parentcomp property 'parent' should be empty
 2. object childcomp property 'parent' should have parentcomp object
 3. And parentcomp property 'links' should have childcomp

    (parentcomp)----LINKS_TO---->(childcomp)

    (parentcomp)<----PARENT----(childcomp)

Note: My equirement is such that we need two way relationship..

But, below is the result when I load parent or child entity

 1. object **parentcomp** property 'parent' has both childcomp,parentcomp 
instead of empty
 2. object **childcomp** property 'parent' has both childcomp,parentcomp 
instead of only parentcomp

This behavior persist until a Neo4j sessions clears out internally. After 
some time(or after app restart) the mappings shows up correctly. 

I tried cleaning up the session using neo4joperations.clear() still problem 
persists. But if I query 

    match (c:Component)-[:PARENT]->(p) where c.componentId = {0} return p

results are correct.

I am not sure how to solve this problem...
