Memory data store is not order preserving
-----------------------------------------

                 Key: GEOT-1258
                 URL: http://jira.codehaus.org/browse/GEOT-1258
             Project: GeoTools
          Issue Type: Bug
          Components: core main
    Affects Versions: 2.3.1
            Reporter: Andrea Aime
            Assignee: Andrea Aime
             Fix For: 2.3.2, 2.4.M2


A Geoserver user noted the inline feature rendering order is not predictable. This is because inline features are put into a memory data store, and the latter is not order preserving, because uses a HashMap instead of a LinkedHashMap. I'm also wondering if a map is really needed, it ensures no two features have the same id, but it seems a little overkill (its memory requirements are far higher than a plain arraylist).
