Nemanja Jovanovic ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMTdjZWRkYmQw... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16714?atlOrigin=eyJpIjoiMTdjZW... ) HHH-16714 ( https://hibernate.atlassian.net/browse/HHH-16714?atlOrigin=eyJpIjoiMTdjZW... ) Caching does not work properly when hibernate.cache.use_structured_entries is turned on ( https://hibernate.atlassian.net/browse/HHH-16714?atlOrigin=eyJpIjoiMTdjZW... ) Issue Type: Bug Assignee: Unassigned Created: 29/May/2023 09:05 AM Environment: Hibernate 6.2.3.Final (core and jcache), Adoptium 17 JDK, HSQLDB (Used in test case) Priority: Major Reporter: Nemanja Jovanovic ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) When hibernate.cache.use_structured_entries is set to true, entities that have superclass are not properly put in cache. Problem is in org.hibernate.sql.results.graph.entity.AbstractEntityInitializer.putInCache , structure from superclass is used for storing cache entry, instead of structure from entity that should be put in cache. This is only a problem when hibernate.cache.use_structured_entries is set to true (see org.hibernate.cache.spi.entry.StructuredCacheEntry.structure vs org.hibernate.cache.spi.entry.UnstructuredCacheEntry.structure ). Gradle test case attached.
