是ServiceConfig的doDelayExport()方法执行时抛出的异常：
```
protected void doDelayExport() {
getScopeModel().getDefaultExtension(ExecutorRepository.class).getServiceExportExecutor()
.schedule(() -> {
try {
doExport();
} catch (Exception e) {
logger.error("Failed to export service config: " +
interfaceName, e);
}
}, getDelay(), TimeUnit.MILLISECONDS);
}
```
可能是getServiceExportExecutor获取到的executor正在做shutdown，获取方法的同步机制有缺陷。
不过我觉得DefaultExecutorRepository的serviceExportExecutor的scope应该改成framework，不应该随着每个application进行shutdown。
