Answer 1

JDK 8兼容性指南在java1.8中声明java编译器(javac)中的更改。详细信息可以在本文档中的概要“针对它们的实现进行编译时需要显示接口”中找到。因此，当使用JDK 8时，在编译过程中必须将缺少接口的类添加到类路径中。

我添加了这个依赖项来解决这个问题。

<dependency>
            <groupId>com.ibm.ws.prereq</groupId>
            <artifactId>commonj-twm</artifactId>
            <version>8.0.0</version>
            <scope>provided</scope>
        </dependency>
