> Problem Summary:
> The FactoryRegistry code is used by the JAX-WS implementation to plug in various implementation factories.
> The factories are put into the registry infrequently (startup).
> The factories are obtained frequently.
> The current code uses a Hashtable to store the factories.  The synchronization degrades performance.
> Solution:
> This solution was proposed by David Strite of the IBM Performance team.  
> We will be removing the Hashtable implementation and replacing it with a "copy on put" pattern as described by:
> http://www.ibm.com/developerworks/java/library/j-hashmap.html
