> My company discovered that there was excessive blocking occurring which was
> tracked down to AbstractJAXBProvider doing synchronizations when checking
> various collections. Instead, using ConcurrentHashMaps and other techniques,
> those synchronizations are only necessary when the collection in fact needs
> modifications, i.e., the first time a specific type is used. After that,
> synchronizations are no longer required and multiple concurrent calls don't
> start blocking each other.
