Oracle Sequence in CDT

There is a table which is using oracle sequence as a PK. I am using below annotations in XSD, the problem here is all the EMP_IDs creating in jumbling order like (1,2,3,4,13,14,5,6).

<xsd:element name="EMP_ID" type="xsd:integer">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">@Id @Column(name="EMP_ID", columnDefinition="NUMBER NOT NULL") @SequenceGenerator(name="EMP_ID_SEQ_generator", sequenceName="EMP_ID_SEQ", initialValue=1) @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="EMP_ID_SEQ_generator")</xsd:appinfo>
</xsd:annotation>
</xsd:element>
