运行java程序时加入
-XX:+PrintFlagsFinal可以打印出JVM启动时所设置的所有的默认flags的值！
本人的JDK的版本情况：
1$ java -version
2java version "1.8.0_151"
3Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
4Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
我们假设启动参数：
1java -XX:+PrintFlagsFinal messageSenderTest.JVMTest2
这样就可以打印出JVM所有flags的默认值啦！
