Jakarta EE Working Group Metrics

As of 2025-11-01

This report provides some basic metrics for Jakarta EE Specification projects, based on commits against repositories claimed by by the projects (as specified in the project metadata (that is, the PMI).

All commits in the listed repositories are included in these queries. Many of these repositories have histories that start when the projects were moved to the Eclipse Foundation; many have histories that predate that move.

The commits for the Jakarta Bean Validation project, for example, start in 2007.

Unless specified otherwise, all data is for the previous full quarter, based on the date that the report was generated. That is, for example, a version of this report generated in September would show (again, unless indicated otherwise) data for the second quarter (April to June), but a version of this report generated in October would show third quarter data.

This report is generated on the first of each month. Reports are generated from live data, so there is some likelihood that — even though subsequent versions of this report describe the same period — there may be some change in the information reported (for example, new repositories may be added; older pull requests may be merged, adding commits to previous periods; or other errors may be corrected). This report is provided as is. Unfortunately, we do not have an option for digging further into these results at this time. Report issues via EMO Team/EMO. Be aware that we have limited bandwidth to address enhancements.
