Cannot apply method security on Spring-data-jpa repositories

I have already posted about this on the security forum, but this issue seems to be restricted to the spring-data repositories.
There seems to be no way to apply method security on Spring-data repositories (neither annotations nor pointcuts will work) unless all methods inherited from the spring-data-jpa interfaces are overridden and secured in the subinterface.
More details and a test project demonstrating the issue can be found at http://forum.springsource.org/showth...a-repositories
