Tenemos una aplicación JSF que estaba en Weblogic 10.3.6 y que intentamos implementar en Weblogic 12.2.1.
Para información, logramos implementar en Weblogic 12.1.3 sin ningún cambio en el proyecto.
Nos enfrentamos a una NullPointerException mientras se implementa en Weblogic 12.2.1:

Como puede ver en el stacktrace, todas las clases involucradas son clases de weblogic y ninguna clase de mi proyecto.
¿Alguien tiene una idea para este problema?
Gracias por adelantado
