> In {{BeanMetaDataCache}} we have a map from {{Class}} to {{BeanMetaDataImpl}}. Currently there is no eviction strategy for this cache meaning entries will never be removed once they were added to the cache and the {{ValidatorFactoryImpl}} holding the cache exists.
> In particular this means that the concerned class objects never can be garbage-collected. This might cause problems in long-running applications (especially as there is typically one long-living {{ValidatorFactory}} instance per application). Maybe {{WeakHashMap}} or similar might be useful here.
