https://hibernate.atlassian.net/browse/HHH-16532?atlOrigin=eyJpIjoiNTcwYm... ) Hibernate entity with @Any attribute throws a nullpointer exception when merging ( https://hibernate.atlassian.net/browse/HHH-16532?atlOrigin=eyJpIjoiNTcwYm... ) Issue Type: Bug Affects Versions: 6.2.0.CR3 Assignee: Unassigned Components: hibernate-core Created: 28/Apr/2023 02:54 AM Priority: Major Reporter: Vincent Bouthinon ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) Hi, I opened a post on the forum org.hibernate.sql.results.graph.Fetchable.asAttributeMapping()" is null - Hibernate ORM - Hibernate ( https://discourse.hibernate.org/t/org-hibernate-sql-results-graph-fetchab... ) The following problem appears when doing a merge of an entity that has an @Any attribute : java.lang.NullPointerException: Cannot invoke "org.hibernate.metamodel.mapping.AttributeMapping.getAttributeMetadata()" because the return value of "org.hibernate.sql.results.graph.Fetchable.asAttributeMapping()" is null at
