---------------------------------------

Hi Gary,

Following is the java code I am using to generate the sample files.

public class CSVUsingLog {
	private static final Logger logger = LoggerFactory.getLogger("auditcsvfile");
	public static void main(String[] args) {
		int val1 = 9, val2 = 11, val3 = 12;
		logger.info("Info Message!", val1, val2, val3);
		logger.info("Info Message!", val1, val2, val3);
		logger.info("Info Message!", val1, val2, val3);
	}
	
}

I run the same code multiple times to test file rollover. I am using the configuration mentioned
in the description.

> The header and first record are coming in first line in case of CsvParameterLayout. This
messes up the header for the first file as well as for the subsequent files. And if we use
line separator as part of header, the first file seems ok but the first record in subsequent
files comes out to be empty with only commas.
