Hi Nicolas,

I found some issues with your example but nothing that could fully explain
the error.

1. In blueprint.xml you use the namespace xmlns:jpa="
http://aries.apache.org/xmlns/jpan/v1.0.0";. This is deprecated. The correct
one is xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0";
2. Your DataSource is not fully JTA enabled. (You are using
org.apache.commons.dbcp2.managed.BasicManagedDataSource)

You can see how to setup dbcp2 in
https://github.com/ops4j/org.ops4j.pax.jdbc/blob/master/pax-jdbc-pool-dbcp2/src/main/java/org/ops4j/pax/jdbc/pool/dbcp2/impl/ds/DbcpXAPooledDataSourceFactory.java

I suggest to simply use pax-jdbc-pool-dbcp2 und pax-jdbc-config to create
your DataSource. See
https://ops4j1.jira.com/wiki/display/PAXJDBC/Pooling+and+XA+support+for+DataSourceFactory

Can you try if fixing these two issues helps?
If not then it might be a bug and I will investigate it deeper.
