	 * Adds the try/catch around the rest execution code.

	 * If an exception is caught, it will first check if the handler is set. If
	 * the handler is set, it will call the handler and return null (or nothing
	 * if void). If the handler isn't set, it will re-throw the exception so
	 * that it behaves as it did previous to this feature.
