[hibernate-issues] [JIRA] (HHH-16244) Cannot delete entities with one-to-one and bidirectional one-to-many relationship

Milad ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZTgzOWQzZWQx... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16244?atlOrigin=eyJpIjoiZTgzOW... ) HHH-16244 ( https://hibernate.atlassian.net/browse/HHH-16244?atlOrigin=eyJpIjoiZTgzOW... ) Cannot delete entities with one-to-one and bidirectional one-to-many relationship ( https://hibernate.atlassian.net/browse/HHH-16244?atlOrigin=eyJpIjoiZTgzOW... ) Change By: Milad ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) I have {{EntityA}} and {{EntityB}}. There exist the following relationships: * One-to-one relationship from {{EntityA}} to {{EntityB}}. * Bidirectional one-to-many relationship from {{EntityA}} to {{EntityB}}. To remove both entities, I first clear all references, then call {{session.remove()}} on both entities. This results in this exception: {noformat}jakarta.persistence.PersistenceException: Converting `org.hibernate.exception.ConstraintViolationException` to JPA `PersistenceException` : could not execute statement at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:165) at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:175) at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:182) at org.hibernate.internal.SessionImpl.doFlush(SessionImpl.java:1429) at org.hibernate.internal.SessionImpl.managedFlush(SessionImpl.java:477) at org.hibernate.internal.SessionImpl.flushBeforeTransactionCompletion(SessionImpl.java:2234) at org.hibernate.internal.SessionImpl.beforeTransactionCompletion(SessionImpl.java:1930) at org.hibernate.engine.jdbc.internal.JdbcCoordinatorImpl.beforeTransactionCompletion(JdbcCoordinatorImpl.java:439) at org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorImpl.beforeCompletionCallback(JdbcResourceLocalTransactionCoordinatorImpl.java:183) at org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorImpl$TransactionDriverControlImpl.commit(JdbcResourceLocalTransactionCoordinatorImpl.java:281) at org.hibernate.engine.transaction.internal.TransactionImpl.commit(TransactionImpl.java:101) at org.hibernate.bugs.ORMUnitTestCase.hhh123Test(ORMUnitTestCase.java:110) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.hibernate.testing.junit4.ExtendedFrameworkMethod.invokeExplosively(ExtendedFrameworkMethod.java:45) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:299) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:293) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.lang.Thread.run(Thread.java:834) Caused by: org.hibernate.exception.ConstraintViolationException: could not execute statement at org.hibernate.exception.internal.SQLExceptionTypeDelegate.convert(SQLExceptionTypeDelegate.java:60) at org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:56) at org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:109) at org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:95) at org.hibernate.engine.jdbc.internal.ResultSetReturnImpl.executeUpdate(ResultSetReturnImpl.java:200) at org.hibernate.engine.jdbc.batch.internal.NonBatchingBatch.addToBatch(NonBatchingBatch.java:39) at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:3763) at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:4116) at org.hibernate.action.internal.EntityDeleteAction.execute(EntityDeleteAction.java:126) at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:612) at org.hibernate.engine.spi.ActionQueue.lambda$executeActions$1(ActionQueue.java:483) at java.base/java.util.LinkedHashMap.forEach(LinkedHashMap.java:684) at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:480) at org.hibernate.event.internal.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:329) at org.hibernate.event.internal.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:39) at org.hibernate.event.service.internal.EventListenerGroupImpl.fireEventOnEachListener(EventListenerGroupImpl.java:107) at org.hibernate.internal.SessionImpl.doFlush(SessionImpl.java:1425) ... 23 more Caused by: org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: Referentielle Integritõt verletzt: "FK8QCPYR2C217Q3RPPCGGGR7ST3: PUBLIC.ENTITYA FOREIGN KEY(SELECTEDENTITYBID) REFERENCES PUBLIC.ENTITYB(ENTITYBID) (2)" Referential integrity constraint violation: "FK8QCPYR2C217Q3RPPCGGGR7ST3: PUBLIC.ENTITYA FOREIGN KEY(SELECTEDENTITYBID) REFERENCES PUBLIC.ENTITYB(ENTITYBID) (2)"; SQL statement: delete from EntityB where EntityBId=?
