[REPORT] Apache Cayenne

[Andrus Adamchik <aa...@apache.org>]

## Description:
Apache Cayenne is a Java persistence framework. It takes a distinct
approach to object persistence and provides an ORM runtime, remote
persistence services, and a GUI mapping/modeling tool.

## Issues:
There are no issues requiring board attention at this time.

## Activity:
There were no releases on the stable (3.1) or alpha (4.0) branches this
past reporting period.  Most effort was directed to 4.0 development
(expecially Remote Object Persistence - ROP) and bug fixes, environmental
updates (such as fixing build failures), and mailing list support.

## Health report:
Cayenne is still under active development and mailing list activity
indicates we have an active and stable community, although with a
summer vacation lull.
