@Contended doesn't work correctly with inheritance

if class annotated by @Contended, its fields must be padded. but they don't padded againts subclasses's fields.

e.g. offset of T1E.int2 and T1E.int3 must be equal to 272 and 276 respectively:

@Contended
class T1 {
    private int int1;
}

class T1E extends T1 {
    private int int2;
    private int int3;
}
