The following classes have a default close method implementation which does not belong and should be removed:

org.springframework.batch.execution.launch.EmptyItemWriter
org.springframework.batch.item.writer.ItemWriterAdapter
org.springframework.batch.item.reader.ItemReaderAdapter

Here's an interesting question -- how do you deal with something that needs to be both an ItemStream and a RepeatInterceptor?

Take org.springframework.batch.io.support.HibernateAwareItemWriter for instance -- suppose you want this to be transaction managed as an ItemStream, how would you do that?
