HibernateDefaultEntityAliasesはNullPointerExceptionを発生させます

Spring Boot、Spring Data REST、Hibernate(5.2.12.Final)を使用しており、リポジトリをRESTサービスとして公開しています。

NullPointerExceptionを発生させるクエリに問題があり、その理由がわかりません。 HTTPリクエストを介してこのメ​​ソッドを呼び出しています(これはSpring Data RESTによって公開されています)。

これはコードです:

@Transactional(readOnly = true)
@PreAuthorize("isAuthenticated()")
public interface CheckPointRepository extends JpaRepository<CheckPoint, Long> {

@Query(value = "SELECT * FROM CheckPoint WHERE (:name IS NULL OR name LIKE CONCAT('%',:name,'%')) ORDER BY name LIMIT 20", nativeQuery = true)
    public List<CheckPoint> findByNameOrderByNameList(@Param("name") String name);

}

これはスタックトレースです:

そのクエリに問題はありません。私は何か間違ったことをしていますか、それともこれはバグですか?

=====================追加および最終情報=====================

何度も試した結果、問題はクエリではなく、エンティティCheckPointに入力したいくつかの式であることがわかりました。

@Entity
public class CheckPoint extends AbstractEntity {
    private static final long serialVersionUID = 2719798641638659883L;

    @Audited
    @NotBlank
    @Column(nullable = false, unique = true)
    private String name;

    private LocalTime openingTime;

    private LocalTime closingTime;

    // The minimum number of ticket that should be present in the checkpoint
    @Audited
    @Min(value = 0)
    @Column(nullable = false)
    private int stockThreshold = 0;

    // Available blocks in this checkpoint
    @Formula(value = "(SELECT COUNT(*) FROM TicketBlock t WHERE t.CheckPoint_id=id)")
    private long availableBlocks;

    @Formula(value = "(SELECT COALESCE(SUM(t.availableTickets),0) FROM TicketBlock t WHERE t.CheckPoint_id=id)")
    private long availableTickets;

これをリポジトリ内のあらゆる種類のネイティブクエリと組み合わせると、その例外がスローされます(これも単純な"FROM CheckPoint")。リポジトリでネイティブクエリの代わりにHQLクエリを作成することを解決しました。もちろん、私が望んでいたものとはまったく異なり、これは回避策のように考えています。 NullPointerExceptionは常にバグだと思います。私よりも専門家がこのトピックに役立つ何かを追加できるかどうか知りたいです。

はい、@FormulaアノテーションとnativeQuery...を使用して、この正確な状況に関するバグレポートがあります。5.1にのみ報告されるため、影響を受けるバージョンとして5.2を追加できます。

私が使用した簡単な回避策(問題の1つはもう機能しないため)は、ネイティブクエリを使用してIDを取得し、次に通常のrepository.findOne(id)を使用して式を使用してエンティティをフェッチします。 、しかしねえ、それは動作します
