/**
 *  Extended version of {@link EJBException} that includes a root cause.
 *  {@link EJBException} doesn't have quite the right constructor for this ...
 *  it has an equivalent to the rootCause property, (causedByException), but
 *  doesn't have a constructor that allows us to set a custom message.
