Description

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,#.##########}

",
