[JAVA] 日常填坑 java.lang.SecurityException: Prohibited package name: java.xxx

package java.patterns.v1;

import capsule.patterns.v1.factory.SendFactory;

public class Test {

/**
 * > 普通工厂模式
 * @param args
 */
public static void main(String[] args) {
//发送
        SendFactory.sendModule("sms").send();
    }

}

报错如下：
