That's particularly aggravating if you have extended ID generation annotations such as

@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idGenerator")
  @GenericGenerator(name = "idGenerator", strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator", parameters = {
      @Parameter(name = "sequence_name", value = "ID_SEQ"),
      @Parameter(name = "initial_value", value = "1"),
      @Parameter(name = "optimizer", value = "<some-PatchedPooledLoOptimizer>"),
      @Parameter(name = "increment_size", value = "1000") })

In this case you need to ensure that the "increment_size" is actually the same as in the DB sequence.
