>                 URL: https://issues.apache.org/jira/browse/DERBY-3275
>             Project: Derby
>          Issue Type: Bug
>          Components: Newcomer, Services
>    Affects Versions: 10.4.1.3
>            Reporter: Knut Anders Hatlen
>            Priority: Minor

> The javadoc for org.apache.derby.iapi.services.cache.CacheFactory.newCacheManager() describes the initialSize parameter like this:
> 		@param initialSize	The number of initial holder objects that will be created
> And org.apache.derby.impl.services.cache.Clock's constructor says the following:
> 		@param initialSize the initial number of cachable object this cache
> 		holds.
> 		@param maximumSize the maximum size of the cache.  The cache may grow
> 		from initialSize to maximumSize if the cache policy notices that there
> 		is not enough free buffers availiable.  Once the cache hits maximumSize
> 		it will not grow.  If the cache is full, an exception will be thrown
> However, when Clock is created, it does not populate the cache with "holder objects" or "cacheable [objects]". It only uses the initialSize to specify the initial capacity of the HashMap and the ArrayList that are created.
> Either the code should be changed so that it's in line with the comments, or the comments should be changed to match the code. I don't see any compelling reason for changing the code, so I think I would prefer changing the comments.
