I have Roo-generated Spring MVC application connected to PostgreSQL using Hibernate. I am trying to integrate Flyway 1.6 as a bean into Spring application context. “Something prevents” migrations from being executed and I’m getting error on context initialization caused by Hibernate metadata validation.
There are no problems performing migrations using Flyway 1.6 Maven plugin (clean, init, migrate).

Integration of Flyway 1.5 (previous version) works just fine.

What should I do in order to make Flyway 1.6 integrated migrations work?
What additional configuration should I provide?

Environment: Ubuntu 11.10, Springsource Tool Suite 2.9.1 (Eclipse 3.7.2), OpenJDK 6b23, Tomcat 7.0.23, PostgreSQL 8.4.9/9.1, Spring 3.0/3.1, Hibernate 3.6.4.Final, PostgreSQL Native Driver 8.4 JDBC3/4 build 702.

    It seems you could be facing the same issue as this: https://github.com/flyway/flyway/issues/107

    Please give the attached jar a test. If it also works for you, I’ll release it as 1.6.1 in the next few days.
