コードを正常に実行すると正常に機能するネイティブSQLクエリに問題がありますが、次のようになります。

[EL Warning]: 2013-01-15 10:24:04.462--UnitOfWork(2230747)--

まったく同じクエリを使用しても、コードを正常に実行してもまったく問題はありません。これが私のpersistence.xmlsです：

persistence.xml（テスト）

PriceRepositoryTest.java-testGetAmountOfPricesForChain1（）

@Test
public void testGetAmountOfPricesForChain1() {
    EntityManagerFactory emf = Persistence.createEntityManagerFactory("test-pu");
    EntityManager em = emf.createEntityManager();
    try {
        PriceRepository repository = new PriceRepositoryImpl(em);
        long amount = repository.getAmount(STORES_IN_CHAIN_1);
        assertEquals(PRICES_CHAIN_1.size(), amount);
    } finally {
        em.close();
    }
}

これをグーグルで検索してみましたが、何も見つかりませんでした。何が間違っている可能性があるかについてのアイデアはありますか？

Oracleデータベースではなく、Derbyに接続しています。Derbyがこの構文をサポートしていない可能性が非常に高いです。
