-----------------------------------

However it does not seem consistent - the declarations for return types are not covered in the same manner - see updated testcase where return value constraints are still left on the concrete class - but still passes.

This is because a strengthening of postconditions in sub-types is no problem in programming by contract. A client of a method just might get more guarantees for the return value than he had expected, but that's fine. This is also consistent with getter based property constraints, there the constraints in a hierarchy are conjoined, too.

BTW: How about distributing https://github.com/gunnarmorling/methodvalidation-integration as hibernate-validator-aspects?

Yepp, this might be an idea. I'm not quite sure how to proceed with the integration project. If you're using Seam/CDI, there is [Seam Validation|http://seamframework.org/Seam3/ValidationModule] but we surely need to find a solution for other stacks, too.
