After doing a Spring / Hibernate upgrade to the latest versions, I hit problems running my tests under maven.
org.springframework.beans.factory.BeanCreationException:

Spring is trying to autowire the Spring beans in the context together but falls over while attempting to create either the transaction manager or the transaction proxy manager factory, it's not clear.

All the classes in the org.permacode project are relatively simple and the whole testing here is aimed around validating the application's implementation and management of the Spring context and transaction handling, hence the local classes in this project like AtomicConfigurationBean and ContextManager. These aren't actually doing anything treacherous other than wrapping the JPA entity manager factory or Spring application context.
I have more than one JPA provider dependency in there, because the project allows swapping between them - it's not an error. I assume it's not a source of the problem since I suspect that cglib or something else to do with proxying is the issue here.
I struggled to find a solution to this yesterday, sifting through a great number of cries for help with BeanCreationException and NoClassDefFoundErrors but generally always some solid class was missing from the victim's classpath. In this situation though Spring is complaining about $proxy10 which I assume is meant to be the name of one or other of the beans configured via IOC.
I'm not just looking for a solution, I would also upvote or accept as an answer good advice on an approach I should take to resolve this from scratch, assuming any epiphany will late in coming.
I stripped out most dependencies and removed large amounts of code until it worked and then started adding the latest version of dependencies back in as I uncommented the code and they became necessary for compilation and testing.
I reached the end of this process without the error resurfacing.
These are the differences in my dependency list:

This is the maven dependency:list output so these are all my dependencies plus the resolved dependencies.
So cglib.jar is out and cglib-nodep is a later version.
Suspiciously, spring-test.jar is also updated because I explicitly depend on it now, otherwise it reverts to that older version. However that on its own doesn't create problems.
It's obviously not my priority to go back now and work out which of these changes solved the issue, I guess it could have been either or both of @raphw or @jhadesdev 's answers.
