Ivy VersionRangeMatcher lower range bug [4.2.0.3,4.2.+]

[Eran Bartenstein <er...@personeta.com>]

Hi,

In my version it seems that there is a bug in the VersionRangeMatcher.
In case the found version is identical to the lower version it is being
discarded by the matcher and the jar is not found.
I checked in the code and it seems that there is a bug in the following
code:

In VersionRangeMatcher (L:83)

The following code doesn't return 0 in case the modules (art1,art2) are
identical in content but not in instances:

	private final Comparator COMPARATOR = new Comparator() {
		public int compare(Object o1, Object o2) {
			if (o1.equals(o2)) {
				return 0;
			}
			ArtifactInfo art1 = new
MRIDArtifactInfo((ModuleRevisionId)o1);
			ArtifactInfo art2 = new
MRIDArtifactInfo((ModuleRevisionId)o2);
			ArtifactInfo art =
getLatestStrategy().findLatest(new ArtifactInfo[] {art1,art2}, null);
			return art == art1 ? -1 : 1;
		}
	};
