Affects: 5.2.6 The javadoc for org.springframework.orm.hibernate5.support.OpenSessionInViewFilter mentions FlushMode.NEVER:

 * <p><b>NOTE</b>: This filter will by default <i>not</i> flush the Hibernate Session,
 * with the flush mode set to {@code FlushMode.NEVER}. It assumes to be used
 * in combination with service layer transactions that care for the flushing: The
 * active transaction manager will temporarily change the flush mode to
 * {@code FlushMode.AUTO} during a read-write transaction, with the flush
 * mode reset to {@code FlushMode.NEVER} at the end of each transaction.

However there is currently no FlushMode.NEVER in org.hibernate.FlushMode, it was removed in hibernate 5.2. Should there be FlushMode.MANUAL?
