I would like to extract some classes from my other project (Raildelays) to contribute more specicaly to the Spring Batch project.

Some of interesting classes :

• CompositeItemStreamReader
• ItemStreamItemReaderDelegator
• AbstractItemCountingItemStreamItemWriter
• SortedItemStreamWriter I have to argue this because it's at the opposite of batch principles (the reader should sort content)
• ExcelSheetItemReader
• ExcelSheetItemWriter
• CompositeJobParametersExtractor and all other extra JobParametersExtractor
• MdcThreadPoolExecutor not based on my own code (I should ask to the author first)
• MdcThreadPoolTaskExecutor not based on my own code (I should ask to the author first)
• ExecutionContextDemotionListener
• ResourceLocator and all the concept behind
