Thanks for the input! I have definitely seen the apache stack while I was looking into OSGi and will definitely explore this route. Thanks for the github references too.
I also am gonna read the Enterprise OSGi in action book to understand more how the lego pieces go together. Hopefully, I will be posting more if I can grok the OSGi concepts.
