如何使用客户端/服务器 Nailgun(在 Debian Stretch 上)运行一个简单的 Java 程序？

How run a simple Java program with the client/server Nailgun (on Debian Stretch)?
我正在尝试在 Debian GNU/Linux 9 (stretch) 上使用 Nailgun。
"Nailgun 是一个客户端、协议和服务器，用于从命令行运行 Java 程序，而不会产生 JVM 启动开销。程序在服务器中运行(用 Java 实现)，并由客户端触发(编写在 C) 中，它处理所有 I/O。"
找到一些文档：
- 钉枪快速入门
- JVM 启动时间/Nailgun
- 如何使用nailgun服务器提高java的性能
- DSpace/钉枪
我使用 Oracle Java 版本 10.0.2(我也尝试使用 GraalVM 1.0.0-rc9 Java 1.8.0_192)。
一个简单的 Java 程序进行测试：
TestVarargs.java。
(最后我想运行一个 JAR 文件，但我尝试过这个简单的例子，因为它不起作用。)
$ wget https://bitbucket.org/OPiMedia/hellanguages/raw/default/Java/standard/TestVarargs/TestVarargs.java
$ javac TestVarargs.java
$ java TestVarargs$ sudo apt-get remove nailgun$ java -jar /usr/share/java/nailgun-server.jar &
NGServer 0.9.1 started on all interfaces, port 2113.$ ng-nailgun ng-version
NailGun server version 0.9.1$ ng-nailgun ng-cp
