The JAX-RS matching algorithm doesn't support mixing of sub-resource methods and locators with the same @Path value, the sub-resource locator is always ignored if there's a sub-resource method with the same @Path. See step 2.f in:
https://jsr311.dev.java.net/nonav/releases/1.1/spec/spec3.html#x3-360003.7.2
I need to think about the implications some more but your use-case could be accommodated by making a change to step 2.c to only add sub-resource method templates when the request method matches.
Could you add an issue in the jsr311.dev.java.net project so we can keep track of this issue and consider it for a subsequent version of JAX-RS.

This would simplify the code of ItemResource considerably (moving PUT and DELETE into the ItemResource forces me to call DB.lookup in all other methods...)
