Junit4: 슈퍼클래스의 @BeforeClass가 실행되지 않음

@BeforeClass 주석 javadoc의 명령문과 반대로:
/** The <strong i="7">@BeforeClass</strong> methods of superclasses will be run before those the current class. */
@BeforeClass 어노테이션이 붙은 수퍼클래스 메소드는 다른 @BeforeClass 가 서브클래스인 경우 호출되지 않습니다.

public abstract class SuperTest {
    <strong i="13">@BeforeClass</strong>
    public static void beforeClass() throws Exception {
        fail("why don't you call me ?");    // never fails
    }
}

public class MyTestA extends SuperTest {
    <strong i="14">@BeforeClass</strong>
    public static void beforeClass() {
        fail("Thanks for calling");     // fails here
    }

    <strong i="15">@Test</strong>
    public void test() {
        fail("Failure expected from MyTestA.beforeClass()");  
    }
}

public class MyTestB extends SuperTest {
    <strong i="16">@BeforeClass</strong>
    public static void beforeClass() {
    }

    <strong i="17">@Test</strong>
    public void test() {
        fail("Failure expected from SuperTest.beforeClass()");    // fails here
    }
}
