Tim, many thanks again for your advices.
Definitely it seemed to be a version conflict problem (as almost every problem in OSGi....). Karaf 4.2.0 comes with a not too updated version of Eclipselink and it brings a version 2.6.1 of the Apache Aries JPA Container adapter for EclipseLink. I unistalled it and installed the last version of Aries Tx Ctrl with the JPA Container adapter Ver. 2.7.1-SNAPSHOT, and now it works. I am performing some test for massive data loading, with different granularity of transactions, nested tx, noRollback exceptions etc... and it seems to be a comfortable choice for a big project I'm carry on. Unfortunally I have still some hang session updating the test bundle in Karaf, often with losing of the JPAEntityManagerProvider that appears again only after a lot of attempts, but I will submit the question to Karaf community, as you suggested. So for now, many thanks for your help.
