>
> Doug Larson did some more profiling and pointed out that on the ProvidersRegistry MediaTypeMap, using a ConcurrentHashMap over SimpleConcurrentMap actually improves performance by a few percentage points.
> {code}
> private final SimpleMap<Class<?>, SoftReference<SimpleMap<MediaType, List<ObjectFactory<T>>>>> providersCache =
> new SimpleConcurrentMap<Class<?>, SoftReference<SimpleMap<MediaType, List<ObjectFactory<T>>>>>(); ;
> {code}
> While the cache keys (Class<?>) would not be WeakReferences, the values would still be SoftReferences.
> Thoughts?
