In SunPKCS11.java, around line 139:

if (slotID < 0) {
    int index = config.getSlotListIndex();
    if ((index < 0) || (index >= slots.length)) {
throw new ProviderException("slotListIndex is " + index
+ " but token only has " + slots.length + "slots");
    }
    slotID = slots[index];
}

The exception message should have a space between slots.length and "slots".
So it should be
slots.length + " slots"

I got this exception before my smartcard was correctly set up. After the
set up, I can't reproduce this exception any more. But the message should
be fixed.
