在Java 10中运行我的Spring引导项目，并且一切正常。 简单地将 JDK 从 10 更改为 11 会引入以下错误

我没有使用Spring Webflux框架，以前也不需要任何带有反应堆框架的罐子。 我知道Java 11从JDK中剔除了很多JEE的东西，但事实并非如此。
我尝试过 SpringBoot 2.0.5 版本和 2.1 的最新里程碑版本 (M4(，结果是一样的。 我将Spring Cloud版本从Finchley.SR1更改为Greenwich.M1，结果相同。
还有其他人遇到过类似的问题吗？ 任何帮助将不胜感激。
编辑：简单地将反应堆核心作为托管依赖项添加到我的 Pom 会导致另一个问题，即它找不到 Netty 库......这很奇怪，因为它应该使用雄猫。
在撰写本文时，根据 Spring Boot 文档，Spring Boot 2.1.0.M4 和 2.0.5.RELEASE 需要 Java 8 或 9 以及 Spring Framework 5.1.0.RELEASE 或更高版本。所以我不认为Spring Boot正式支持Java 11。
