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 Aries JPA

/63 | Active | 80 | 2.3.0 | Apache Aries JPA

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

/karaf@root()>/
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.

Reading your post again Christian I realize that I should

I seem to have JPA 2.0 and JPA 2.1 installed at runtime:

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.
