 for resource caching.  The current default is

-which uses a LRU Map to prevent data from being held forever.  You can
-set the size of the LRU Map using the parameter

+<code>org.apache.velocity.runtime.resource.ResourceCacheImpl</code>.
+When <code>resource.manager.defaultcache.size</code> is set to 0, then
+the default implementation is the standard java ConcurrentHashMap.
+Otherwise, a non-zero cache size  uses an LRU Map.  The default cache size
+is 89.  Note that the ConcurrentHashMap may be better at thread concurrency.
