Android.app.Fragment $ InstantiationException: Tratando de instanciar una clase ScannerFragment que no es un fragmento

He actualizado algunas bibliotecas en app.gradle como la biblioteca de soporte de 22.2.0 -> 23.0.0 y versiones de algunas bibliotecas de terceros, y ahora estoy recibiendo el siguiente error de ejecución en una actividad en particular:

En particular, esta línea parece extraña:

• Java.lang.ClassCastException: android.app.Application no se puede enviar a greendroid.app.GDApplication
• ¿Cómo establecer el ancho y la altura para la vista personalizada en forma programática?
• Classcastexception android en inicio de actividad
• Android.app.Application no se puede convertir en android.app.Activity
• Cualquier método alternativo para Casting de clase

 Caused by: android.app.Fragment$InstantiationException: Trying to instantiate a class com.example.shubhamkanodia.bookmybook.Fragments.ScannerFragment that is not a Fragment 

(ScannerFragment es un fragmento que implementa el escáner de código de barras dm77 que actualizé de 1.7.2 a 1.8.2)

Fragmento del escáner:

¡Cualquier ayuda sería apreciada!
