Benjamin M. ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5f1862a... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiOGRjOTZlMmMy... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-14113?atlOrigin=eyJpIjoiOGRjOT... ) HHH-14113 ( https://hibernate.atlassian.net/browse/HHH-14113?atlOrigin=eyJpIjoiOGRjOT... ) Entity Graph attribute resolution not based on selected entity ( https://hibernate.atlassian.net/browse/HHH-14113?atlOrigin=eyJpIjoiOGRjOT... ) Change By: Benjamin M. ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5f1862a... ) I was trying to fetch an entities association and have that fully initialized (will be serialized to JSON): {code:sql}SELECT u.groups FROM User u WHERE u.id = ?1{code} Applying a Named/Ad Hoc Fetch Graph yields an Exception. E.g. for this Graph: {code:java}EntityGraph<Group> eg = em.createEntityGraph(Group.class); eg.addAttributeNodes("permissions");{code} I get: {quote}org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list \[FromElement\{explicit,collection join,fetch join,fetch non-lazy properties,classAlias=u,role=com.example.assocFetchGraph.persistence.User.permissions,tableName=\{none},tableAlias=permission3_,origin=null,columns=\{,className=null}}]{quote} That is because both classes have a `permissions` property. Expected behavior would be, that the Fetch Graph's attributes would be resolved relative to Group, not User. (But the JPA spec doesn't seem to be very clear here). I have created a reproducing example: [https://github.com/cptwunderlich/assocEntityGraphMRE|https://github.com/c...] We had a discussion about this on Zulip #hibernate-user "EntityGraph resolution" I also created a StackOverflow question: [https://stackoverflow.com/questions/63015923/jpa-select-association-and-u...] I provde an excerpt of the code here for your convenience: {code:java}@Entity public class User { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Enumerated(EnumType.STRING) @ElementCollection(targetClass = Permission.class) @CollectionTable(name = "USERS_PERMISSIONS", joinColumns = @JoinColumn(name = "uid")) private Set<Permission> permissions = EnumSet.of(Permission.FOO); @ManyToMany(fetch = FetchType.LAZY) private Set<Group> groups = new HashSet<>(); } @Entity @NamedEntityGraph(name = Group.ENTITY_GRAPH, attributeNodes = { @NamedAttributeNode("permissions") }) public class Group { public static final String ENTITY_GRAPH = "group-with-permissions"; @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Enumerated(EnumType.STRING) @ElementCollection(targetClass = Permission.class) @CollectionTable( name = "GROUPS_PERMISSIONS", joinColumns = @JoinColumn(name = "gid") ) private Set<Permission> permissions = EnumSet.noneOf(Permission.class); } // Query: List res = em.createQuery("SELECT u.groups FROM User u WHERE u.id = ?1") .setParameter(1, u.getId()) .setHint(GraphSemantic.FETCH.getJpaHintName(), em.getEntityGraph(Group.ENTITY_GRAPH)) .getResultList();{code} Stack Trace is: { quote noformat

Interestingly, in my actual code, I have and additional JOIN FETCH for a ManyToOne and I get the above Exception for that additional property.
