Mockito @InjectMocks annotations on superclasses of test class are ignored

PowerMock does not support '@InjectMocks' annotations on superclasses of a 
testclass. This feature has been improved in Mockito 1.9.0 and is particularly 
useful for testing applications that make extensive use of Dependency Injection.

Here is an example that demonstrates the problem (it throws a 
NullPointerException):

interface Something {
    void invoke();
}

class ObjectUnderTest {
    private final Something _something;

    ObjectUnderTest(final Something something) {
        _something = something;
    }

    void performOperation() {
        _something.invoke();
    }
}

@Ignore
public abstract class BaseTest {
  @Mock
  Something _something;
  @InjectMocks
  ObjectUnderTest _objectUnderTest;

  @RunWith(PowerMockRunner.class)
  public static class PerformOperationTest extends BaseTest {
    @Test
    public void performsTheOperation() {
      _objectUnderTest.performOperation();

      verify(_something).invoke();
    }
  }
}
