Similar to other answers, but I prefer to use a companion object instead of alternate constructors.

class MyException(message: String, cause: Throwable = null) extends Exception(message, cause)

  def apply(message: String): MyException = new MyException(message)
  def apply(message: String, cause: Throwable): MyException = new MyException(message, cause)
}
