* This class defines a Directory Server task that can be used to shut down or

* NOTE: This class, and other classes within the
* {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
* supported for use against Ping Identity, UnboundID, and
* Nokia/Alcatel-Lucent 8661 server products. These classes provide support
* for proprietary functionality or for external specifications that are not
* considered stable or mature enough to be guaranteed to work in an
* interoperable way with other types of LDAP servers.
*
*
* The properties that are available for use with this type of task include:
*
*
A flag that indicates whether to shut down the server or to perform
* an in-core restart (in which the server shuts down and restarts itself
* within the same JVM).
*
An optional message that can be used to provide a reason for the
* shutdown or restart.
