> In "LeastSquaresFactory.java" at line 487, a cast is performed that will fail when the "model" argument is not instantiated with the "model" method (defined at line 278).
> A fix could consist in the methods defined in (currently internal, line 291) class "LocalMultivariateJacobianFunction" becoming part of the public API, in an extension of the "MultivariateJacobianFunction" interface.
> The contructor of "LocalLeastSquaresProblem" (at line 371) should then throw an exception if lazy evaluation is requested but the "model" does not implement the appropriate interface.
