我尝试在网上挖掘以解答我的问题。我找到了一些与 Project DaVinci 相关的文档。这被标记为JSR 292，它与在JVM中包含闭包有关。这个项目是否实现了，它是Java 8的一部分吗？

推荐答案
据我所知，Java 8没有尾部呼叫优化。 Afaik它与实际的编译器技巧无关，因为它很简单，但为了安全起见保留了一个callstack。但我想用字节码重写器是可能的。
As far as I know Java 8 does not have tail call optimization. Afaik it isn't related to the actual compiler trick, because that one is simple, but to preserve a callstack for security purposes. But I guess it would be possible with a bytecode rewriter.
