Just a thought. How about creating a Jira and adding your process there
> Hi Everyone,
>
> My name is Anton Mazkovoi, and I am one of the JIRA developers at
> Atlassian. We are very happy users of OfBiz Entity Engine and have been
> using it in JIRA for the past 3.5 years, to manage all of JIRA's
> persistence.
>
> Firstly, please let me thank every one who has contributed to OfBiz
> Entity Engine, as it has helped us a great deal! Thank you all for
> putting together this wonderful framework.
>
> JIRA has been "stuck" on OfBiz Entity Engine 2.1.1 for a few years now,
> and time has come to upgrade!
>
> The first decision we have to make is whether to upgrade to the latest
> source in SVN or the snapshot of EE that is shipped with opentaps 0.9.0.
> As we have some patches to merge into the code (I will send details on
> these in another e-mail) we would prefer to go with the latest source. I
> would really appreciate if you could give me some insight on its
> stability and readiness for production prime time.
>
> I would also be very interested to know, if it is possible to use the
> GeronimoTransactionFactory to manage transactions in various application
> servers (i.e. not just Geronimo). Has anyone tried this?
>
> I would also love to hear from anyone who has upgraded from 2.1.1 to the
> latest Entity Engine builds. Are there any guides available that
> describe the required steps? So far I have found:

> However, I have noticed that the package names in EE had "core" removed.
>
> Are there any other things people have come across that we should keep
> in mind during the upgrade?
>
> During the years of Entity Engine 2.1.1 usage, we have patched a few
> things. Some of them seem to be in the latest source already. However,
> there are still some things that are not there. I will follow up with
> another e-mail describing the patches we have come up with, as we would
> like to get them committed, if possible.

> Thanks,
> Anton

> P.S. Please forgive me if this e-mail should have been sent to the
> "users" list instead. As I plan to follow up with an e-mail discussing
> patches, to keep the thread in one place, I chose the dev list.
