   原因是：Since 6.6.0, SkyWalking cancelled the local span and exit span register. If old java agent(before 6.6.0) is still running, and do register to 6.6.0+ backend, you will face the following warning message.
   
   所以就会出现这个告警：class=RegisterServiceHandler, message = Unexpected endpoint register, endpoint isn't detected from server side.
   
   解决方法如下：/skywalking/config/log4j2.xml
   新增一个规则：
   **<logger name="org.apache.skywalking.oap.server.receiver.register.provider.handler.v6.grpc.RegisterServiceHandler" level="ERROR"/>**

   完整配置如下：
   <Loggers>
   		<logger name="org.apache.skywalking.oap.server.receiver.register.provider.handler.v6.grpc.RegisterServiceHandler" level="ERROR"/>
           <logger name="org.eclipse.jetty" level="INFO"/>
           <logger name="org.apache.zookeeper" level="INFO"/>
           <logger name="io.grpc.netty" level="INFO"/>
           <Root level="info">
               <AppenderRef ref="RollingFile"/>
           </Root>
       </Loggers>
