Hmm this could actually explain the problems we see. I always wondered
why karaf insists to install the 2.1 version of the jpa spec bundle but
this explains it.
Luckily this should be easy to solve. Try to install the OSGi jpa spec
bundle:
http://search.maven.org/#artifactdetails%7Corg.osgi%7Corg.osgi.service.jpa%7C1.0.0%7Cjar
It should contain exactly the missing package. I think we are missing
this bundle in the feature. We just did not see it as it is embeded in
the jpa 2.1 spec bundle we use.
You could also try to simply add this bundle to the persistence-api
2.0.0 feature. Maybe then karaf already does the right thing.

It seems like the or.apache.aries.jpa.container requires the package
org.osgi.service.jpa (at least version 1.0.0) and that package is only
provided by the JPA 2.1 bundle...
Hope you understand this a bit better than me but it does not seem to
be easy to come up with a working solution including OpenJPA 2.4.1 in
Karar 4.0.5. If you have a workaround to try before you get a fix inte
Karaf 4.0.6 I would be grateful.

Genereally Aries JPA should work with OpenJPA 2.4.1 but I
think there is some bug in karaf 4.0.5.
I just tested again and found that persistence api 2.0 and 2.1
are both installed. This fails as Aries JPA can only bind to
one of these and will choose the higher version.
As a workaround you should be able to create your own feature
copied from the Aries JPA feature but make sure you install
the persistence api only in version 2.0.
I will try to create a working version of the features for
karaf 4.0.6.

Installing feature "openjpa" also installs JPA 2.0 (version
1.1) so I shouldn't need to install JPA manually as well.
However, then I won't get the Aries support for JPA. Feels a
bit weird.
What Aries JPa version should be used together with OpenJPA
2.4.1?

It seems to be the "jpa" feature that installs JPA 2.1.

On a fresh Karaf 4.0.5 I do:
/la | grep -i jpa/
/la | grep -i persistence/
Nothing is displayed. I then do:
/feature:install openjpa jpa
/
If I then execute the above commands I get:
/karaf@root()> la | grep -i jpa/
/62 | Active | 80 | 2.3.0 | Apache

/55 | Active | 80 | 2.1.0.v201304241213 | Java

So JPA 2.1 has indeed been installed. I don't know if
this is why I have problems but it still seems strange.

Can you start from an empty karaf 4.0.5 and then do
feature:install openjpa jpa
This should install openjpa 2.4.1 and aries jpa
2.3.0 with javax.persistence 2.0 and jta 1.2.
This configuration should work. So maybe
something else you install requires the jpa 2.1 spec.

I don't really know why the JPA version 2.1
(2.1.0.v201304241213) is being installed. I do
not do this explicitly.
Looking at OpenJPA 2.4.1, it seems to depend on
JTA 1.1 not JTA 1.2.
Looked again at my JPA version. I do use JPA
2.0. But I use version 1.1 of
artifact geronimo-jpa_2.0_spec which caused me
to believe I was using JPA 1.1....
I'm still kind of confused. It would be thankful
if you could tell me what features (and versions
of those features) I should install in order to
use the latest version (2.4.1) of OpenJPA.
