The exception occurs when a class has a method with a non-empty parameter list with the same name as the field that is being extracted. E.g. :

trait T[A]
object O {
      private def x[A: T]: Int = ... // a method with an implicit parameter
      private def x: Int = 42
}

ReflectionUtils.extractFieldValue(O, "x") // throws an exception!
