[lyo-dev] Keep Uses order

[Guillaume Dufour <guillaume.duff@xxxxxxxxx>]

Hello,

I am using an OSLC Requirement Server with OSLC. And I see that requirement uses URI don't keep the order from OSLC Server because it's store in a TreeSet.

https://github.com/eclipse/lyo.client/blame/master/oslc-java-client/src/main/java/org/eclipse/lyo/client/oslc/resources/RequirementCollection.java#L40

TreeSet use natural order comparator to sort element. But natural order have no sens for URI.

So I propose to use LinkedHashSet which keep the order provide by OSLC Server.

Can I provide a PullRequest for this ?

If you are ok, which the best way to do the PR : gerrit or github ?

Regards
