TestNG disable all inherited test methods

I'm using TestNG framework, and many test classes extends Base abstract Test providing some additional information.

I want to set @Test(enabled = false) on whole test class, which is problematic in TestNG as any @Test annotation on method will override first one. Which means, even disabled class, all methods will run anyway.

I found workaround provided by framework authors in pull requests #816 - add listener, that modifies @Test annotations on methods if class that they are defined have @Test(enabled = false):

public class TestClassDisabler implements IAnnotationTransformer {

  @Override
  public void transform(ITestAnnotation annotation, Class testClass, Constructor testConstructor,
                        Method testMethod) {
    if (testMethod != null) {
      Test test = testMethod.getDeclaringClass().getAnnotation(Test.class);
      if (test != null && !test.enabled()) {
        annotation.setEnabled(false);
      }
    }
  }
}

It works like a charm, however only for tests that don't use inheritance. For this scenario, testMethod.getDeclaringClass() from listener returns original class in which method was declared, not class of object instance that started method.

@Test(enabled = false)
class SpecificTest extends BaseTest {

    @Test
    public void testSomething() {}
}

abstract class BaseTest {

    @Test
    public void veryGenericTest() {}
}

For this example, only testSomething is disabled, veryGenericTest still runs.
