jdk9,11不能运行加密后的jar包

[wangsanshi123]

写了一个简单的demo，就是打印hello world,发现用jdk8加密后的包，只能用jdk8运行，用jdk9加密后的包，也只能用jdk8跑。 否则会报错： WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by io.xjar.reflection.XReflection (file:/root/tmp9/encrypted9.jar) to field java.net.URLClassLoader.ucp WARNING: Please consider reporting this to the maintainers of io.xjar.reflection.XReflection WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release Exception in thread "main" java.lang.reflect.InaccessibleObjectException: Unable to make public jdk.internal.loader.Resource jdk.internal.loader.URLClassPath.getResource(java.lang.String) accessible: module java.base does not "exports jdk.internal.loader" to unnamed module @c2e1f26 at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:340) at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:280) at java.base/java.lang.reflect.Method.checkCanSetAccessible(Method.java:198) at java.base/java.lang.reflect.Method.setAccessible(Method.java:192) at io.xjar.reflection.XReflection.method(XReflection.java:35) at io.xjar.jar.XJarClassLoader.(XJarClassLoader.java:41) at io.xjar.jar.XJarLauncher.launch(XJarLauncher.java:51) at io.xjar.jar.XJarLauncher.main(XJarLauncher.java:31) panic: exit status 1

goroutine 1 [running]: main.main() /root/tmp9/xjar.go:86 +0x630

总结一下：

加密 | 运行 | 是否报错 jdk8 | jdk8 | 否 jdk8 | jdk11|是 jdk9 |jdk9 |是 jdk9|jdk8 |否

我在网上查了下，说是jdk高版本不支持这个方法，大佬看下高版本jdk有没有替换的方法

这里是在网上对java.lang.reflect.InaccessibleObjectException的答案：https://www.coder.work/article/61641 网上说是jdk9以后引入的一个问题

我也遇到了一样的问题，我是JDK11。但无奈软件要求使用JDK11，因此放弃了XJAR
