> The BracketingNthOrderBrentSolver used by the EmbeddedRungeKuttaIntegrator
> fails, if an event is detected twice with a NoBracketingException.
> The problem lies in line EventState.java line 262 (version 3.1.1). Here the
> event detection function f is applied to an arbitrary choosen value of time.
> If the event detector crosses zero before this time, the solver throws the
> mentioned exception.
