spec: descriptions of isCached() and isCachedFile() are incorrect

Name: mlR10151 Date: 03/20/2001



The following classes:
   FileCacheImageInputStream
   FileCacheImageOutputStream
   MemoryCacheImageInputStream
   MemoryCacheImageOutputStream
do cache data, and isCached() methods of these classes return true, as expected.

But the descriptions of the isCached() and isCachedFile()
methods say that default implementation returns false.
