GenerationType.SEQUENCE for Oracle sequence

Hibernate Tools
1

I’d like to have generated a sequence strategy like this manually written one (which works against my Oracle sequence):

@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="MY_SCHEMA.SQ_ID")

I tried (with hibernate-tools-maven-plugin-5.6.14.Final)

<table name="MYTABLE" schema="MY_SCHEMA" >
	<primary-key>
		<generator class="sequence">
			<param name="sequence">MY_SCHEMA.SQ_ID</param>
		</generator>
		<key-column name="ID" />
	</primary-key>
</table>

but hbm2java creates

@SequenceGenerator(name="some.package.MyTableIdGenerator")
@Id 
@GeneratedValue(strategy=SEQUENCE, generator="some.package.MyTableIdGenerator")

How can I make it create an annotation like the manually written one above?

Thanks,
Juergen
