You can create custom exception the "symfony way" let's look at how exception or created in symfony:

first create your customExceptionInterface

namespace My\SymfonyBundle\Exception;
/**
 * Interface for my bundle exceptions.
 */
interface MySymfonyBundleExceptionInterface
{
}

And create your jsonErrorException

namespace My\SymfonyBundle\Exception;

class HttpException extends \Exception implements MySymfonyBundleExceptionInterface
{
}

Don't hesitate to browse symfony's exceptions code examples on github
