All Implemented Interfaces:

java.io.Serializable
```
public class GSSException
extends java.lang.Exception
```
This exception is thrown whenever a fatal GSS-API error occurs including mechanism specific errors. It contains both the major and minor JGSS status codes. The mechanism implementers are responsible for setting appropriate minor status codes when throwing this exception. Methods are included to retrieve the error string representation for both major and minor codes.
RFC 2078
GSS-API major status codes are divided into fatal and informatory status codes. In JGSS, fatal codes are represented using exceptions of this class, and informatory codes are returned through instances of the MesssageProp class used in the GSSContext methods. This class also provides the functionality of gss_display_status.

    minorCode - the mechanism specific error code
    
    message - textual explanation of the mechanism error code
  - toString
```
public java.lang.String toString()
