Benjamin, I suppose the result makes sense. In essence, Maven is becoming multi-threaded. What about wrapping the LinkedHashMap instances with Collections.synchronizedList()? Perhaps it is a natural progression of Maven's stability: 2.0.9 introduced one LinkedHashMap, 2.0.10 converted them all, and now 2.1 should probably synchronize on them.
