Troubleshooting Guidance Support Diagnostic Patterns
之前一直發現rlim_fd_max這個值始終都是預設的1024這個值，並不是user設定後的值，原來是在啟動的時候，他會去跑commEvn.sh裡頭的resetFd()這個function，裡頭會把值還原成1024，把它comment掉就好了。

Smartly load your properties
Link
Example
Assume I have a property file which named config, and this file locate at src/albert.
This file contains two values:
name=albert
email=junyuo@gmail.com
Then you can utilize this approach to read this property file
InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("albert/config.properties");
PropertyResourceBundle rb = new PropertyResourceBundle(is);
System.out.println("name="+rb.getString("name"));
System.out.println("email="+rb.getString("email"));
