Title: Refactor code to support building against Java 1.6 including Travis testing

The code now compiles and tests with Java 1.6, too.

I kept source compatibility settings in `pom.xml` set to `1.7` though to preserve the existing Java version setup.

To verify you only need to change:

```xml
1.7
1.7
```

to

```xml
1.6
1.6
```

and -- after ensuring your JDK version in use is actually 1.6.x -- you can run `mvn clean test`.
