- ## Constructor Details

  - ### SaslException

    public SaslException()
    Constructs a new instance of `SaslException`. The root exception and the detailed message are null.

  - ### SaslException

    public SaslException(String detail)
    Constructs a new instance of `SaslException` with a detailed message. The root exception is null.
    Parameters:

      - `Throwable.getMessage()`

  - ### SaslException

    public SaslException(String detail, Throwable ex)
    Constructs a new instance of `SaslException` with a detailed message and a root exception. For example, a SaslException might result from a problem with the callback handler, which might throw a NoSuchCallbackException if it does not support the requested callback, or throw an IOException if it had problems obtaining data for the callback. The SaslException's root exception would be then be the exception thrown by the callback handler.
    Parameters:
      `detail` - A possibly null string containing details of the exception.
      `ex` - A possibly null root exception that caused this exception.
