Spring Cloud Config Client - Angel.SR4 vs Boot 1.3.1? - spring-boot

Question

All,
I've built Spring Cloud Config servers and clients before with previous versions of Spring Cloud / Spring Boot, but I seem to be having an issue with the Angel.SR4 / Boot 1.3.1 combination.
Following the basic instructions here (http://projects.spring.io/spring-cloud/docs/1.0.3/spring-cloud.html#_client_side_usage), except using the current releases of Boot and Cloud (1.3.1.RELEASE / Angel.SR4 at present), I get the following stack trace:

If I back off the Boot version to 1.2.8 the problem disappears. If I move Cloud up to Brixton.M4 the problem disappears. Is there a prescribed version combination of Boot / Cloud that should be used together? Thanks in advance.

Is there a prescribed version combination of Boot / Cloud that should be used together?
Yes. Angel is Boot 1.2, and Brixton is Boot 1.3. See the blog for more detail: https://spring.io/blog/2015/11/25/migrating-spring-cloud-apps-from-spring-boot-1-2-to-1-3
