I did:

https://issues.jenkins-ci.org/browse/JENKINS-17869

Is there any chance to revert somehow? Downgrading to 1.504 gives me the same error now.

Hmm, is the component correctly set in Jira, it is accurev? The actual plugin seems to be hudson.plugins.global_build_stats.GlobalBuildStatsPlugin

Did you downgrade that plug-in?

I have no idea which component causes the problem. The selected component is the first found in the component list.

The component list contains tons of entries and how should I know which one to choose? The compontent field

in the bug tracker should be optional.

If you don't select a component, the person who is most likely to be able to help, will probably miss the bug. Since there are so many developers developing plugins and so forth on Jenkins, selecting the component can really help get the issue resolved faster.

Wha do you want to tell me? I reported a migration issue of the Jenkins core...so what module should I select? Should I dig through a list of a hundred

components without having knowledge about the internals of Jenkins?

If its Jenkins core, then you could select "core" as the component.
