Use of well-known libraries to refactor sources

We can make use of Google Guava, a very well-know libraries which leverages all the tips mentioned in the book Effective Java.

i personally like the guava library, used it a lot for caching mechanisms. I think a good use would be later in some kind of persistence layer on top of the s7connector (like hibernate and consorts)...

For several byte operations, we can make use of Guava. If possible, you can also investigate the sources where we can make use of Guava.
