I think I found a failure, in the processChangeReferenceData() method you check the value of P1 instead of P2 at the beginning of the method:

// Checks the value of P2
if (buf[ISO7816.OFFSET_P1] != 0x80)
ISOException.throwIt(ISO7816.SW_INCORRECT_P1P2);

it probably should be:

// Checks the value of P2
if (buf[ISO7816.OFFSET_P2] != 0x80)
ISOException.throwIt(ISO7816.SW_INCORRECT_P1P2);

thank you for your excellent tutorial and all the work you have put in this!
