    How contributors participate in this community?


      Hi, I am a phd student of Peking University. My interest is to

      investigate hybrid projects (open source and backed by companies), e.g,

      how it affects volunteers compared to the beginning open and free world.

      I studied jboss through its log files in SVN, issue reports in Issue

      Tracker, emailing-lists and information all over Internet, found some

      interesting results, also have a couple of questions, hope any of you

      wouldn't mind reading and answering.


      JBoss seems to go through four periods since is was born in 1999.

      period1: 2000.04-2001.03, pure open source project

      period2: 2001.06-2004.02, hybrid project under JBoss Group LLC., aimed to Offering professional services

      period3: 2004.06-2006.02, hybrid project under JBoss Inc., claimed to build "Professional Open Source"

      period4: 2006.10-2010.08(to the date of my investigation), hybrid project under Redhat, to build "Professional Open Source"

      If I'm wrong, please correct me.


      1) It seems that JBoss gets less external developers after Redhat's

      acquiring -- I identified external developers through their

      emails (according to the domain of the contact email addresses in JIRA, mail-list archives: with domains “@jboss.org”, “@jboss.com”, or

      “@redhat.com” to be internal for JBossAS; otherwise, to be extenal).

      Is that because a new protocol requires a long process to get commit

      privilege? Or, people just simply didn't like any commercial companies

      getting involved therefore ran away? E.g, "There had been rumors

      swirling about various people leaving JBoss after its acquisition by Red

      Hat, including Marc Fleury." (See



      I also observed that Geronimo showed the similar phenomena IBM stepped

      in. I suppose commercial involvement might hurt people in open source to

      some extent, I wonder what it is.


      2) However, I found JBoss developers stay longer after JBoss LLC./Inc.

      was founded and especially after Redhat acquired it.

      It looks like JBoss Inc. and Redhat hired a lot people working on it.

      I guess people would be happy if they are paid to do something they are

      happy to do. This is the bright side of hybrids, isn't it?

      Are there any specific strategies Redhat would do to keep experienced

      people who have been contributing a long time in the project?



      3) People always say one big advantage of oss is to have a big amount of

      users reporting issues therefore help improve quality. However, I found

      less issues are reported by users after Redhat acquired JBoss. Is

      that because many users tend to post questions and issues on on JBoss

      Community Forum where the response is faster? Or is that because

      Redhat restrict the usage of JIRA so as to ensure the issue quality,

      such as it requires users to first ask in forum then in JIRA?


      I also found developers are the majority of issue reporters, not only in

      jboss, but also in geronimo nowdays. I was wondering, is that because

      jira is more for developers now (users r in forum)? Or, developers are

      required to report before jumping into fixing/changing code?


      I believe what JBoss is doing has great implications for software

      engineering, e.g, how to build a better community, what are the best

      practices to attract participators. I would greatly appreciate any

      comments you might have.
