    `ClassFormatException​(String message, Throwable cause)` | Constructs a new instance with the specified detail message and cause.

- - ### Constructor Detail

    - #### ClassFormatException

          public ClassFormatException()

      Constructs a new instance with `null` as its detail message. The cause is not initialized, and may subsequently be initialized by a call to `Throwable.initCause(java.lang.Throwable)`.

    - #### ClassFormatException

          public ClassFormatException​(String message)

      Constructs a new instance with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to `Throwable.initCause(java.lang.Throwable)`.
      Parameters:
        `message` - the detail message. The detail message is saved for later retrieval by the `Throwable.getMessage()` method.

    - #### ClassFormatException

          public ClassFormatException​(String message,
                                      Throwable cause)

      Constructs a new instance with the specified detail message and cause.

      Note that the detail message associated with `cause` is not automatically incorporated in this runtime exception's detail message.

      Parameters:
        `message` - the detail message (which is saved for later retrieval by the `Throwable.getMessage()` method).
        `cause` - the cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)

    - #### ClassFormatException

          public ClassFormatException​(Throwable cause)

      Constructs a new instance with the specified cause and a detail message of `(cause==null ? null : cause.toString())` (which typically contains the class and detail message of `cause`). This constructor is useful for runtime exceptions that are little more than wrappers for other throwables.
      Parameters:
        `cause` - the cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)
