In the doc comment for CardException and CardNotPresentException, the first sentence of one of the constructors is rendered incorrectly, because of a bad interaction with the doclet's determination of the first sentence.

Specifically, the following comment:
     * Constructs a new CardNotPresentException with the specified cause and a detail message
     * of <code>(cause==null ? null : cause.toString())</code>.
causes the first sentence to end prematurely at the "?", which is bad in and of itself, but also causes the generated HTML to be broken because of the unbalanced <code> that appears in theose contents where just the first sentence appears.
