所有已实现的接口:

Closeable, Flushable, AutoCloseable

public class BufferedOutputStreamWithCloseDetection
extends BufferedOutputStream

Workaround for stream close issue under Java 8. The problem is: during Workbook writing to stream, Apache POI closes output stream itself. After that, ExcelWriteStep closes this stream also because it was open in the ExcelWriterStep. But Java 8 contains bug https://bugs.openjdk.java.net/browse/JDK-8042377 with second stream closing. As result, second close() throws exception.
