Answer 1

经过一番挖掘，我发现 IllegalArgumentException 是由 Jersey 重新打包的 ASM 库引发的。

我不能确定我的版本是否正确，但在第 170 行，代码如下:

    // checks the class version
    // added "support" for java 9 compiled classes
    if (readShort(off + 6) > Opcodes.V9) {
        throw new IllegalArgumentException();
    }

代码正在检查它尝试读取的类的类文件版本号，如果版本太新，则抛出 IllegalArgumentException。

简而言之，您正在尝试使用一些使用 Java 编译器编译的 Java 类，而该编译器对于 ASM 库来说太新了:

• 使用较旧的 JDK 或将 -target 版本设置为较旧的版本。
• 或者，查找/安装经过您正在构建的 Java 版本认证的 Jersey 版本。

令我感到奇怪的一件事是，您对 POM 文件中的旧版本“asm”有明确的依赖。但是，堆栈跟踪表明您没有使用该版本。
