As a part of deploying the OpenJDK portal we are also including some of the basic quality metrics for the JDK 7. The goal behind this is to provide insight into the quality processes used in the development cycle and quality of the release it self.

The OpenJDK Quality Metrics page is at http://openjdk.java.net/groups/quality/metrics/index.html.

We have taken the Goal - Question - Metric approach (look here or here for details) with the initial goal of "Explain the quality and related processes". More about the planned goals (and questions/metrics) will be published soon on this blog.

For the first phase we have created just two metrics - the overall defect flow and the flow of regressions. Both of the charts are available in a version showing absolute (# of defects)

and relative (%) numbers:

Each of the charts is available on both the overall and component level so you can see the status the whole Java as well as the work being done on Swing, JDBC or any other component you are interested in. On the general level some additional stats are available - total # of defects (in various states), RFEs, etc:

All the charts are accompanied with a list of defects that were either Submitted, Fixed or Closed in the last 7 days to better show what the lines in the charts mean (a sample list of submitted/fixed/closed defects is here. The bug lists are linked with the bugs.sun.com database. Yet they are showing some information that is not (yet) available on bugs.sun.com.

At this stage the charts and lists of defects will be re-generated automatically, once per day and published on the portal at around 8 AM GMT.

Enough theory, go look for your self and let us know, what you think ..
