依赖资源安装

1. 安装alsa包 
   yum install alsa-lib-devel
2. 安装cups-devel 
   yum install cups-devel
3. 安装X相关的库 
   yum install libX*
4. 安装g++ 
   yum install gcc gcc-c++
5. 安装freetype 
   yum install freetype-devel
6. 安装libstdc
   yum install libstdc++-static
7. 安装ant 
   unzip apache-ant-1.8.2-bin.zip
8. 设置环境变量

   unset CLASSPATH
   unset JAVA_HOME
   // 语言选项，必须设置
   export LANG=C
   // Bootstrap JDK的安装路径，必须设置
   export ALT_BOOTDIR=/opt/jdk1.7.0_60
   // Ant的安装路径
   export ANT_HOME=/opt/compile/apache-ant-1.8.2
   // 允许自动下载依赖
   export ALLOW_DOWNLOADS=true
   // 预编译
   export USE_PRECOMPILED_HEADER=true
   // 64位jdk
   export ARCH_DATA_MODEL=64
   // 并行编译的线程数，设置为和CPU内核数量一致即可
   export HOTSPOT_BUILD_JOB=4
   export ALT_PARALLEL_COMPILE_JOBS=4
   // 编译内容
   export SKIP_DEBUG_BUILD=false
   export SKIP_FASTDEBUG_BUILD=true
   export DEBUG_NAME=debug
   // 输出路径
   export ALT_OUTPUTDIR=/opt/compile/build-jdk

9. 解压openjdk-7u40-fcs-src-b43-26_aug_2013.zip
   unzip openjdk-7u40-fcs-src-b43-26_aug_2013.zip
10. 编译检查 
    进入解压后的openjdk目录下执行命令：make sanity 
    若输出结果为：Sanity check passed，表示检查通过
11. 执行编译 
    执行命令：make，执行结束后如下，显示每个模块的编译所用时长：

12. #-- Build times ----------
    Target debug_build
    Start 2016-09-05 08:01:45
    End   2016-09-05 08:38:17
    00:03:31 corba
    00:09:33 hotspot
    00:00:36 jaxp
    00:00:45 jaxws
    00:20:55 jdk
    00:01:12 langtools
    00:36:32 TOTAL
    -------------------------

13. 配置debug版jdk 
    /opt/compile/build-jdk-debug/j2sdk-image下内容为debug版jdk，将其复制到%JAVA_HOME%下，替换Oracle JDK。
14. 查看jdk版本信息 
    [[email protected] ~]# java -version 
    
    openjdk version "1.7.0-internal-debug"
    OpenJDK Runtime Environment (build 1.7.0-internal-debug-root_2016_09_05_07_41-b00)
    OpenJDK 64-Bit Server VM (build 24.0-b56-jvmg, mixed mode)

解决方法：报错的位置是openjdk目录下jdk/src/share/classes/java/util/CurrencyData.properties文件，将此文件中所有的时间改为10年以内即可
