 * JVM.
 * <BR><BR>
 * Note that there are two significant differences between this thread and the
 * shutdown task thread (other than the obvious difference that this one does a
 * restart while the other does a shutdown):  this class extends
 * <CODE>java.lang.Thread</CODE> instead of
 * <CODE>org.opends.server.core.DirectoryThread</CODE>, and this thread is not a
 * daemon thread.  These changes are needed to guarantee that the JVM does not
 * exit before we get a chance to restart it if all non-daemon threads go away.
