Question

从eclipse学习和探索Java 9。我在eclipse中创建了一个简单的项目，虽然当我编译项目时，它会打印程序的预期结果，但也会出现以下异常。

Could not instrument class mymodule/App: java.lang.IllegalArgumentException

Java代码：

package mymodule;

import java.util.List;

public class App {

    public static void main(String[] args) {
        List<String> immutables = List.of("Food", "Water", "House");
        System.out.println(immutables.get(0));
    }

}

module-info.java文件

module mymodule { 

}

似乎Eclipse还没有迁移到完全兼容Java 9的 ASM_6.0 。

另一方面，您正在查看与 BUG#526383 类似的堆栈跟踪，您可以按照相同的内容进行更新。

无法检测类IllegalArgumentException
