1. 安装源码管理工具

yum install mercurial

2. 下载源码

hg clone http://hg.openjdk.java.net/jdk8u/jdk8u jdk8u
#执行源码下载命令
sh get_source.sh 
#jdk下载可能会报错
wget http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/archive/f0b93fbd8cf8.zip

5. 编译

make clean （多次编译，清除之前的数据）
make 

6. 测试用例测试

public class JvmTest {
 public static void main(String[] args) {
  System.out.println(System.getProperty("user.home"));
  System.out.println(System.getProperty("java.version"));
  System.out.println(System.getProperty("os.name"));
  System.out.println(System.getProperty("java.vendor.url"));
 }
}
