Example 41 with CollectionEntry

use of org.hibernate.engine.spi.CollectionEntry in project hibernate-orm by hibernate.

the class MultipleSessionCollectionWarningTest method testUnsetSessionCannotOverwriteConnectedSesssionFlushed.

Example 42 with CollectionEntry

use of org.hibernate.engine.spi.CollectionEntry in project hibernate-orm by hibernate.

the class MultipleSessionCollectionWarningTest method testUnsetSessionCannotOverwriteNonConnectedSesssion.

@Test
