找不到方法

java.lang.NoSuchMethodException: java.security.AccessControlContext.getContext()

解决方法

private void cleanProtectionDomainWhichCameFromModuleJarClassLoader() {

        // got ProtectionDomain[] from URLClassLoader's acc
        final AccessControlContext acc = unCaughtGetClassDeclaredJavaFieldValue(URLClassLoader.class, "acc", this);
        //final ProtectionDomain[] protectionDomainArray = unCaughtInvokeMethod(
        //        unCaughtGetClassDeclaredJavaMethod(AccessControlContext.class, "getContext"),
        //        acc
        //);

       // 通过反射字段获取值，增加jdk兼容性
       final ProtectionDomain[] protectionDomainArray = unCaughtGetClassDeclaredJavaFieldValue(AccessControlContext.class, "context", acc);

}
