When we read search criterias into user-populations.xml file, the criterias are stored in an HashMap. It should be a LinkedHashMap to keep the original order defined into the file.

AbstractPopulation.java, line 286 :

_searchCriteriaMetadataPath = new HashMap<String, Map<String, String>>();

Should become :

_searchCriteriaMetadataPath = new LinkedHashMap<String, Map<String, String>>();
