Question

我的小组刚刚升级到java 8，并且有一些代码java.util.Optional映射代码似乎是罪魁祸首。

我们有很多这样的代码行，当然如果我们将它们评论出服务器启动就好了。

但是，我在其他组项目中使用了此可选映射sytax，并且在升级到java8时从未出现过问题。

有什么想法吗？运行jetty-9.2.5.v20141112

// this one definitely causes the server from starting up
// if you comment it out it start up just fine
java.util.Optional<DateRange> Dates = _obj.map(FactoryObject::getEntity).map(Entity::getDates);

错误：
