java.lang.ExceptionInitializerError with Java-16 |j.l.ClassFormatError accessible: module java.base 不 “open java.lang” to unnamed module
我在 Maven 项目中具有传递依赖关系。尽管添加了我认为是正确的,但我无法让该库与Java 16一起使用。cglib
--add-opens
如何使用 Java 16?我在github页面上提出了这个问题。cglib
最小可重现性示例:
Main.java
import net.sf.cglib.proxy.Enhancer;
public class Main {
public static void main(String[] args) {
new Enhancer();
}
}
使用 Java 15:
javac -cp cglib-3.3.0.jar Main.java
java --add-opens java.base/java.lang=ALL-UNNAMED -cp cglib-3.3.0.jar:asm-7.1.jar:. Main
Picked up _JAVA_OPTIONS: -Duser.language=en -Duser.country=GB
