Description

Currently the JPA EdmProvider stores all EDM objects within a simple HashMap. This results in a different metadata document ordering per request. This is problematic when creating a md5 hash for the metadata document to generate an etag for clients.

Changing this to a LinkedHashMap will solve this without changing the API.
