In case of an attitude transition during an propagation with Ephemeris, a "OUT_OF_RANGE_SIMPLE" exception will be thrown.

This is due to a check in the getPVCoordinates method of Ephemeris, that will check that the current date is the same as the computed state date. In case of an attitude transition, if we try to compute the attitude during the transition period, the propagator needs the attitude at the end of this period, so this check will fail.
