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.
