The method short javacard.framework.APDU.setIncomingAndReceive() returns negative values if more than 128 Bytes are received. Seems like a problem with casting a byte to a short variable.

As a workaround I use a method like this: private short apduSetIncomingAndReceive(APDU apdu){ short len = apdu.setIncomingAndReceive(); if (len < 0){ len = (short) (len & 0xff); } return len; }

I think this is the same issue as fixed in issue #27
