The script is used for encrypting the datasource passwords on jboss servers [ref][jboss-wiki].

The flow is as follows:

1. Encrypt the plain texts of passwords
2. Change the *-ds.xml files, like

<!-- REPLACED WITH security-domain BELOW
<user-name>admin</user-name>

Problem statement:

We still used sun proprietary API (sun.misc.BASE64Decoder, sun.misc.BASE64Encoder), which gives compilation warnings. So someday, I decide it to the codec replacement.

BASE64 codec choices:

• apache commons
• javax.xml.bind
• java8 BASE64 API

I like this one better: http://programmers.stackexchange.com/questions/232971/implementation-difference-between-lombok-autovalue

AutoValue is a standard Java annotation processor, meaning that it uses only the javax.* interfaces for annotation processing. 
Lombok is also an annotation processor, but it references implementation-specific classes in order to do things that standard processors 
cannot. Most notably, it changes the code being generated for source classes, for example by inserting getter and setter methods. 
The standard for annotation processors very deliberately did not allow that because it was felt to violate Java's WYSIWYG qualities.

Currently, I used diff=astextplain, what does it exactly do? http://stackoverflow.com/questions/28146244/what-is-the-difference-between-diff-and-diff-astextplain

In today's team meeting, I learned an important that generally the constructor injection should be used as possible over setter injection.

• Historically the setter-injection camp come from spring, whereas constructor-injection camp are from pico-container and GUICE. [ref][ref-1]
• constructor injection is the way to indicate the class design problem, like if you have multiple dependnecies (usually more than three dependencies), you should re-think about the class redesign [ref][ref-2]
• More comprehensive article with bounce of refences [ref][ref-3]

But in the team meeting, my teammate argues from the unit test perspective, which I dont think it makes too much sense, as we are using Spock to deal with the unit testing, and it can handle static or private fields pretty well.
