    - #### ExecutionException

          protected ExecutionException()

      Constructs an `ExecutionException` with no detail message. The cause is not initialized, and may subsequently be initialized by a call to `initCause`.

    - #### ExecutionException

          protected ExecutionException(String message)

      Constructs an `ExecutionException` with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to `initCause`.
      Parameters:
        `message` - the detail message

    - #### ExecutionException

          public ExecutionException(String message,
