It’s Only Software

This post is to expand on some of the thoughts I posted on the SpringSource Blog in response to Rod Johnson’s excellent description of the SpringSource business model and its commitment to development of open source software.

Now that SpringSource has shown an ability to crank out new product releases on a seemingly weekly basis, I wanted to reflect on where Spring is positioned in the Java open source community, and how open the Spring Core project is to work done by the public.

The hypothesis of my experiment occurred to me when I happened to be reviewing Spring JIRA assignments one day. I was curious whether, following the bug assignments, the majority of development on the “Spring Core” projects (including Spring MVC and what we would consider “classic Spring”) is performed solely by SpringSource employees.

I decided to go about verifying this and would like to present my findings. Note that this is a purely objective study of a particular widely used open source project, and shouldn’t be construed as an opinion on the findings.

Edit Sept 22, 2008 Please note that although the publishing of this post by freakish timing occurred less than 24 hours after the announcement by SpringSource, I want to be clear that this article was drafted and published before I was aware of this news. As such, please don’t misread this investigation as a “response” to the announcement.

Since SpringSource is obviously a private company, I determined the list of employees by consulting publicly available information sources. Anyone is welcome to refute the claims in this article.

I have no direct working relationship with anyone at SpringSource; however, to verify the facts cited in my study, I did email an advance copy of the article to Juergen Hoeller, Spring Project Lead. Juergen kindly took the time to review it and clarify a couple facts that I wasn’t able to discern through public information. Juergen has always been friendly and considerate in the dealings we’ve had through Spring JIRA or the Spring forums, and I appreciate the help!

Cross-posting here in case any of my regular readers are interested. I made my first post to the Edgewater Corporate Blog on the subject of moving legacy applications to the web. It’s not really technical, but gives more of a high level view of some of the (many) considerations I (and others) have run into. I’d love to hear what you think of it!
