Collect multiple artifacts and add trace log

Remove the premature break so multiple artifacts can be detected and accumulated from Class-Path URLs instead of stopping at the first match. Add a trace-level log (guarded by logger.isTraceEnabled()) when an artifact is resolved for easier debugging and to avoid unnecessary string construction. Minor formatting cleanup.
