JPA がアルファベット順の列を持つテーブルを生成するのはなぜですか?

+--------------------+--------------+------+-----+---------+----------------+
| Field              | Type         | Null | Key | Default | Extra          |
+--------------------+--------------+------+-----+---------+----------------+
| id                 | bigint(20)   | NO   | PRI | NULL    | auto_increment | 
| name               | varchar(255) | NO   |     | NULL    |                | 
| organizationNumber | varchar(255) | NO   | UNI | NULL    |                |
