OptimisticLockException when updating row with Oracle DATE mapped @Version property in Hibernate

Issue

• An entity version property is defined as

      @Version
      private java.sql.Timestamp updatedAt;
  

• The Oracle DATE type was chosen to map the version property when (manually) creating the underlying table in the database

• Update fails (sometimes randomly) with a write failure

  javax.persistence.OptimisticLockException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
