运行java程序时，报错：

java.security.AccessControlException: access denied("java.lang.RuntimePermission", "getClassLoader")

JDK有一些安全限制，可以修改配置文件文件​​jdk目录/conf/security下java.policy​​，禁用这些限制：

permission java.lang.RuntimePermission "getClassLoader";
permission java.lang.RuntimePermission "createClassLoader";
permission java.lang.RuntimePermission "setContextClassLoader";
