Claus Ibsen wrote up a nice blog post about how Apache Camel did this year using some easily obtained metrics. I thought it was kind of interesting so I wanted to do the same for CXF.
Number of posts on the users list: 6614
Number of posts on the dev list: 1661
Number of messages on commits list (svn commits and wiki changes and such): 3893
Number of JIRA issues raised in 2009: 595
Number of JIRA issues resolved in 2009: 763
Number of JIRA issues raised in 2009, but still unresolved: 51 (only 19 are bugs, 3 are bugs in JAXB where we need a new release of JAXB and 5 were logged in the last 2 weeks while most devs were on vacation, so really 11 bugs unresolved).
The JIRA stats are kind of interesting. Put in a graph:
You can kind of see that the last 4 months or so, the CXF community really tried to go through all the old JIRA entries and resolve as many as possible. The result should be a much more stable and bug free product.
