Using flush() before close()

As per the java docs, invoking close() on any java.io Streams automatically invokes flush(). But I have seen in lot of examples, even in production codes, developers have explicitly used flush() just before close(). In what conditions we need to use flush() just before close()?

Both examples provided are essentially thin wrapper classes, so their flush and close implementations delegate to the underlying stream. I can't see how this alone could lead to any problems, as long as any "real" or buffering streams do flush when being closed.

However I realize that the behavior is not (and can't be) enforced by the javadoc of Closeable.close().
