Yes, you are right. With the correct code:
public static void main(String[] args) {
UUID uuid = UUID.randomUUID();
TestTable1 testTable = new TestTable1(uuid);
persist(testTable);
}
the exception is:
Hibernate: insert into test_db.public.test_table_1 (description, my_id)
values (?, ?)

Surely you want to persist a TestTable1 instance, not the uuid itself.
