Kate Dreaper ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYmVhZmRlNjQ4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-17078?atlOrigin=eyJpIjoiYmVhZm... ) HHH-17078 ( https://hibernate.atlassian.net/browse/HHH-17078?atlOrigin=eyJpIjoiYmVhZm... ) Memory leak in ScrollableResultsConsumer ( https://hibernate.atlassian.net/browse/HHH-17078?atlOrigin=eyJpIjoiYmVhZm... ) Issue Type: Bug Affects Versions: 6.2.7 Assignee: Unassigned Components: hibernate-core Created: 14/Aug/2023 18:10 PM Priority: Major Reporter: Kate Dreaper ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) The ScrollableResultsConsumer ( https://github.com/hibernate/hibernate-orm/blob/bbee6cd4aa2b7b302be16e071... ) registers the jdbcValuesSourceProcessingState in the LoadContexts. But deregister is never called with the jdbcValuesSourceProcessingState like it is in the ListResultsConsumer ( https://github.com/hibernate/hibernate-orm/blob/bbee6cd4aa2b7b302be16e071... ) , resulting in entities referenced in PreLoadEvent and PostLoadEvent never being dereferenced and cleaned up by GC. This can also be seen by loadContexts.isLoadingFinished() returning false after closing the stream.
