A peer deletes a context when the context is no longer needed. In JGSS operations, each peer unilaterally decides when to delete a context and does not need to inform its peer.
JGSS does not define a delete context token. To delete a context, the peer calls the dispose method of the GSSContext object to free up any resources used by the context. A disposed GSSContext object may still be accessible, unless the application sets the object to null. However, any attempt to use a disposed (but still accessible) context throws an exception.
