I can't start my EPP 5.2 server with my custom ecmdemo based container

Issue

I'm migrating from EPP 5.1 and I created a custom Site Publisher container based in "ecmdemo". It works in EPP 5.1, but I can't start EPP 5.2 with it using a local-tx datasource. The following exception is throw:

javax.jcr.RepositoryException: You cannot rollback during a managed transaction!: You cannot rollback during a managed transaction!

How can I can get it working in EPP 5.2?
