We have setup numerous Github repoes that post on SQS upon push.

Jenkins (Github SQS plugin) sees these messages but does not start a build. All we see in the log files are:

Feb 03, 2013 4:45:42 PM com.base2services.jenkins.github.GitHubTriggerProcessor processGitHubPayload
INFO: Received Message for https://github.com/<user>/<code-repo>
Feb 03, 2013 4:45:42 PM com.base2services.jenkins.github.GitHubTriggerProcessor processGitHubPayload
INFO: Poked <project-for-code-repo>

And then nothing else. The last logged line match:
https://github.com/jenkinsci/github-sqs-plugin/blob/master/src/main/java/com/base2services/jenkins/github/GitHubTriggerProcessor.java#L60

which in turn calls
https://github.com/jenkinsci/github-sqs-plugin/blob/master/src/main/java/com/base2services/jenkins/SqsBuildTrigger.java#L66

After this I'm not quite sure what happens (where does the queue come from?). How do I add more verbose log output to follow this call chain?

Does something swallow an exception further down?

Thank you in advance,
Brian
