- ## Constructor Details

  - ### 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.
    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.
    Since:
      6.0

  - ### 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.
    Since:
      6.7.0
