destroy需要加上ServiceInstancesChangedListener的destroy，否则AddressRefreshRetryTask会一直运行，导致后续测试类执行失败：
从代码来看，scheduler使用了Application的ExecutorRepository，这个组件会在应用关闭时shutdown
所持有的ExecutorService资源，不应该会一直执行。可以打开线程检查看一下是否所有线程被清理。
```
mvn test -DcheckThreads=true
```
```java
...
this.scheduler = ScopeModelUtil.getApplicationModel(serviceDiscovery
== null || serviceDiscovery.getUrl() == null ? null :
serviceDiscovery.getUrl().getScopeModel())
.getExtensionLoader(ExecutorRepository.class).getDefaultExtension().getMetadataRetryExecutor();
...
if (hasEmptyMetadata(newRevisionToMetadata)) {// retry every 10
seconds
if (retryPermission.tryAcquire()) {
retryFuture = scheduler.schedule(new
AddressRefreshRetryTask(retryPermission, event.getServiceName()), 10_000L,
TimeUnit.MILLISECONDS);
logger.warn("Address refresh try task submitted.");
}
logger.error("Address refresh failed because of Metadata Server
failure, wait for retry or new address refresh event.");
return;
}
...
```
