Ambiguous method overloading for method grails.spring.BeanBuilder#registerBeans

Question

I'm following Mike Kelly's brilliant tutorial videos but I have been stumped by the following problem. It happens when I add a new Domain Class. I've tried backing out changes and adding a DomainClass with a different name, restarting the IDE, etc. With only one Domain Class I have no error, if I add one the error appears.

I'm working with ggts 3.4.0, Grail 2.3.1, JDK 1.7.0_45.

This is a bug. I was able to reproduce the problem when I was investigating http://jira.grails.org/browse/GRAILS-10735 .
