Polishing
Groovy-based bean definitions

Formerly known as the Grails BeanBuilder, now in Spring proper. Based on https://github.com/spring-projects/spring-framework/pull/355 but heavily refactored and restructured.

Issue: SPR-7123
Upgraded to JCache 0.11 for Spring Framework 4.0 RC1

Unfortunately, the JCache API changed quite a bit since 0.6. We're building against a snapshot of JCache 0.11 now, tracking its way to final after the Public Review Ballot.
