No error is displayed when ordering a number of tickets outside of int range

When checking out an order with ticket count that isn't within Java int range, no error is shown.

Request with ticket count outside int range isn't processed correctly and results in an uncaught org.codehaus.jackson.JsonParseException.

Create booking page expects a JSON response after the order form is submitted, but because of the uncaught exception, an application server error page is returned instead. Because of that, no error is displayed on the page.

Server log with the exception is attached.
