Incremental Seam Validator does not validate subclasses.

How it should work:
1. EXECUTE: Create seam war project.
2. EXECUTE: Create ClassA.java:

public class ClassA {}

3. EXECUTE: Create ClassB.java:

@Stateful
@Name("comp")
public class ClassB extends ClassA {
}

4. EXECUTE: build project.
5. ASSERT: There is an error marker: Stateful component must have a method marked @Remove
6. EXECUTE: Add @Remove to ClassA:

public class ClassA {
@Remove
public void foo() {}
}

7. EXECUTE: build project.
8. ASSERT: Validator removes the error marker.

But now only cleaning/building the project or changing ClassB makes Validator see changes for ClassB.
