Although this framework is fully functional and stable, since it was released Splunk have now created their own Java Modular Inputs librarys. So I recommend that you use the formally Splunk developed and supported offering that can be found here : http://dev.splunk.com/view/java-sdk/SP-CAAAER2

This is a framework for building Splunk Modular Inputs in Java

It contains several example Modular Inputs that you can use as a practical reference to follow.
