Why does my CCM plugin cause a StackOverflowError in Launch callback handler?

I have been developing a server-side participant plugin against my development copy of CCM 4.0.3. I was successfully able to deploy and use it locally during development.

After I installed Jazz and CCM 4.0.6 locally to match our new production environment, and deployed my plugin to this new installation, I am getting the following error in my Tomcat window: 

INFO: Deploying web application archive C:\Program Files\IBM\JazzTeamServer_406_Dev\server\tomcat\webapps\ccm.war

The steps I took are:

  1. Install Jazz server and apps (v.4.0.6).
  2. Upgrade my RTC client from 4.0.3 to 4.0.6.
  3. Clear feature and plugin jars from my plugin's update-site.
  4. "Rebuild All" in update site and copy update site to server/conf/ccm/sites to match previous setup
  5. Copy old provision profile .ini file to new location
  6. Start server

Please let me know what other information I might need to provide to diagnose this.

I figured out my issue. I must have clicked "compute dependencies" on my plugin feature.

To fix, I recreated my dependencies by manually replacing the computed dependencies (plugins) with their respective server features as explained in the IBM Rational Team Concert 4.x Extensibility Lab.

Looking at the source of installFeature , it looks like it calls itself recursively as it walks your dependency graph. So I'm guessing my dependencies were circular, causing installFeature to overflow the stack.
