Instance of abstract class with hidden constructor

I need to create an instance of an abstract class with hidden constructor, the class looks like the following:

public abstract class TestClass {
    /**
    * @hide
    */
    public TestClass() {
    }
}

creating an concrete class does not work, because the constructor is not visible and calling the constructor via reflection API also doesn't work because the class is abstract.

I need to create an instance of android.print.PrintDocumentAdapter.LayoutResultCallback
