    - #### JspTagException

          public JspTagException(java.lang.Throwable rootCause)

      Constructs a new JSP Tag exception when the JSP Tag needs to throw an exception and include a message about the "root cause" exception that interfered with its normal operation. The exception's message is based on the localized message of the underlying exception.

      This method calls the `getLocalizedMessage` method on the `Throwable` exception to get a localized exception message. When subclassing `JspTagException`, this method can be overridden to create an exception message designed for a specific locale.

      Parameters:
        `rootCause` - the `Throwable` exception that interfered with the JSP Tag's normal operation, making the JSP Tag exception necessary
      Since:
        2.0
