Does class#getDeclaredFields() return synthetic fields?

Does the method class#getDeclaredFields() return synthetic (compiler-generated) fields? The Javadoc only says:

Returns an array of {@code Field} objects reflecting all the fields declared by the class or interface represented by this {@code Class} object. This includes public, protected, default (package) access, and private fields, but excludes inherited fields.

Apparently it does. Like @Matteo NNZ pointed out: An inner class generates a synthetic field for "this", so:

public class A {

    public static void main(String[] args) {
        System.out.println(B.class.getDeclaredFields()[0].isSynthetic());
    }

    class B {
    }
}

prints true.
