I forgot it. MathUserException should completely disappear from ODE, and maybe fom other packages too like solvers or optimizers. In fact, even if it does not disappear completely, I would suggest user to not use it anymore and use their own unchecked exceptions. Users can define a class that does not throw this exception even if the interface declaration does specifies it (but the other way round is forbidden: you can't add a checked exception not declared in the interface). best regards, Luc > > Best regards, > Dennis > > > luc.maison...@free.fr wrote: > > Hi Dennis, > > > > ----- Mail original ----- > >> Hi Luc, > >> > >> question: is there a reason you applied this to StepHandler, but > >> not > >> FixedStepHandler? > > > > No, I simply forgot it.
