Tengo un proyecto en el que deseo actualizar la versión de Java 1.7 a Java 1.8, pero al ejecutar UnitTests todas las pruebas de mapeador fallan.

El proyecto está utilizando: SpringJUnit4ClassRunner

<dependency>
    <groupId>ma.glasnost.orika</groupId>
    <artifactId>orika-core</artifactId>
    <version>1.4.5</version>
</dependency>

Para esa parte de la excepción:nested exception is ma.glasnost.orika.MappingException: java.lang.RuntimeException: java.io.IOException: invalid constant type: 15 at 142 Encontré u.a esta publicación SO:Reflections - Java 8 - tipo constante no válido
Pero no estoy seguro de si este es realmente el problema, ya que no tengo dependencia del 'javassist'.

¿Está relacionado con el mismo problema? ¿Cómo puedo superar eso?

StackTrace más completo:
