Requesting a SNAPSHOT artifact from a RELEASE Repo returns HTTP 400

Requesting a SNAPSHOT artifact from a RELEASE repo results in a HTTP 400 response e.g. http://localhost:8081/repository/maven-releases/com/foo/1.0-SNAPSHOT/foo-1.0-SNAPSHOT.jar

 Expected:

Version policy validation for a GET seems excessive and instead attempting to retrieve a (non-existent) snapshot from a release repo should simply return a 404.
