Finally got around to trying this out myself. I'm not seeing your error, but I am seeing a different error that was introduced with some recent changes that Luke made to spring security. This is what mine looks like:
Can you verify that you've done a "clean install" from the project root? I'm wondering if you haven't compiled the changes in the parent pom and in the runtime library...
java.lang.ClassCastException: org.springframework.beans.factory.config.RuntimeBeanReference cannot be cast to java.util.List
Currently in the process of figuring out the fix for the CCE. It would be nice if you could get to the point where you're reproducing what I'm seeing.
