当我在我的本地 Google App Engine 应用程序中将日志记录级别更改FINE为时，我开始在我的跟踪堆栈中看到这些：

Apr 17, 2013 4:54:20 PM com.google.appengine.tools.development.DevAppServerServersFilter getCurrentServerInstance
FINE: Exception getting server instance

任何想法这是什么以及如何解决它？

这是开发服务器中的一个已知问题：
https ://code.google.com/p/googleappengine/issues/detail?id=10412

已经知道有一段时间了，所以我不确定他们是否会修复它。

我认为当您将日志记录设置为 FINE 时，您应该期待一些虚假的日志消息。我只为您的代码将日志记录级别设置为 FINE，并将其余部分保留为默认级别。
