> ode.nonstiff.AdaptiveStepsizeIntegrator.filterStep(double h, boolean forward, boolean acceptSmall) can generate misleading Exception message, for example:
> org.apache.commons.math.ode.IntegratorException: minimal step size (0) reached, integration needs 0
> This is because the message uses {0} and {1} to report the value of doubles.
> The code should really use a number format which allows for more decimal places, e.g.
> "minimal step size ({0,number,#.#########}) reached, integration needs {1,number,#.##########}",
