What prevents Spring Data JPA 1.0.2.RELEASE from using Spring Data Commons 1.2.0.RC1? Even Spring Data JPA 1.1.0.M1 uses Spring Data Commons 1.2.0.M1?

So far in the open source project I'm working at using the latter combination poses no problems.

Right now, I'm testing with Spring Data JPA 1.0.2.RELEASE and by default uses Spring Data Commons 1.1.0.RELEASE with no problems as well.
