            Reporter: Christian Niehues

I get a NullPointerException just right after the restart of my karaf 4.0.3 after installing hibernate with jpa and some relatated features:

Here is how to reproduce it. I am really new to karaf and aries so these are some commands I collected from examples/tutorials for JPA with karaf:
- start a clean initial karaf 4.0.3
- feature:repo-add pax-jdbc 0.7.0
- feature:install hibernate jpa
- feature:install jdbc pax-jdbc-config pax-jdbc-pool-dbcp2 transaction
- restart karaf

The exception doesn't appear everytime, so maybe some more restarts are needed. I hope you can reproduce it with that.
