在org.apache.servicecomb.common.rest.RestEngineSchemaListener注册之前 kafka消费消息调用接口，导致后续调用该接口都报空指针异常

create MicroserviceVersions日志打印早于instance registry succeeds for the first time

通过日志上下文可以确定这个日志是调用一个@RpcReference的接口触发的。但是按理currentStatus 不为UP调用接口应该会抛错。

分析了一天，现象就像是 org.apache.servicecomb.provider.pojo.Invoker#invoke里SCBEngine.getInstance().ensureStatusUp() 在服务状态没有变成UP的情况下依然没有报错正常返回导致的。但是想不出原因。

忽略 是我们自己调用了getOrCreateVersionedCache
