No, the discount curve seems fine (or the engine would blow at the first
iteration.)  My guess is that you don't pass to your Jibar index the
risk-free curve:

without a term structure, the Jibar above can return past fixings but
not forecast future ones.  If you replace the Jibar constructor above
with

new Jibar(new Period(Frequency.Quarterly), DiscountingTermStructure)

it might work (unless there are other similar places in the code that
we're not seeing...)
