FreeBSD中编译JDK

<div align="left">
<br>
<font size="2" style="color: rgb(0, 0, 128);"><span style="font-family: Tahoma;">自从JDK 1.1.8后，FreeBSD 因为在 Java 授权上的种种问题，已经不能发布预编译的 JDK 软件包，也没有了所谓的 Official Release 了。<br><br>现在要在FreeBSD上使用最新的Java技术，需要通过下面的方式自己编译并进行安装：</span></font>
<br>
<br>
<font size="2" style="color: rgb(0, 0, 128);"><span style="font-family: Tahoma;">(1)  FreeBSD + Linux compatibility enable + Linux Process FileSystem mounted</span><strong style="font-family: Tahoma;"><br></strong><span style="font-family: Tahoma;">(2)  </span><a href="https://sdlcweb2a.sun.com/ECom/EComActionServlet;jsessionid=87C3FD20D3BCF5947A0487512406E315" rel="noopener noreferrer" style="font-family: Tahoma;" target="_blank"><strong>Linux Platform - Java(TM) 2 SDK, self-extracting file</strong></a><strong style="font-family: Tahoma;"><br></strong><span style="font-family: Tahoma;">(3)  </span><a href="http://www.sun.com/software/communitysource/j2se/java2/download.xml" rel="noopener noreferrer" style="font-family: Tahoma;" target="_blank"><strong>SCSL (Sun Community Source Licensing) Source</strong></a><strong style="font-family: Tahoma;"><br></strong><span style="font-family: Tahoma;">    -SCSL Source</span><strong style="font-family: Tahoma;"><br></strong><span style="font-family: Tahoma;">    -SCSL Binaries - needed to complete source build</span><strong style="font-family: Tahoma;"><br></strong><span style="font-family: Tahoma;">    -Mozilla Binaries</span><strong style="font-family: Tahoma;"><br></strong><span style="font-family: Tahoma;">(4)  </span><a href="http://www.eyesbeyond.com/freebsddom/java/" rel="noopener noreferrer" style="font-family: Tahoma;" target="_blank"><strong>BSD Java porting patchsets</strong></a></font>
<br>
<br>
<font size="2" style="color: rgb(0, 0, 128);"><span style="font-family: Tahoma;">编译实际上是在FreeBSD的Linux兼容模式下，以Linux JDK Binary为基础，将SCSL Source打上BSD的patch后，在FreeBSD上面编译出native的JDK版本！（哇塞，真是拗口~~~！！！）</span></font>
<br>
<br>
<font size="2" style="color: rgb(0, 0, 128);"><span style="font-family: Tahoma;">所以，以FreeBSD 5.4 Release为例子，我们第一步要做的就是修改 /etc/fstab 这个文件，新增：</span></font>
