      Description



      Name: mlR10151 Date: 04/09/2001



      The spec. for the FileCacheImageOutputStream.close() says:

      public void close() throws IOException
            Closes this FileCacheImageOututStream. All pending data is flushed to the output, and the cache
            file is closed and removed. The destination OutputStream is not closed.

      But the close() does not remove cache file.
      Though VM does remove the file on exit, the spec. says that file
      must be removed by the close() function.
      Note, that FileCacheImageInputStream.close() does remove the cache file.
