Hi, I'm not sure if anyone else uses the SimpleLog class - anyway I've noticed that SimpleLog.log is not thread-safe. The following code (starting on line 282): if(showDateTime) { buf.append(dateFormatter.format(new Date())); buf.append(" "); } makes an unsynchronized call to dateFormatter.format. As dateFormatter is an instance variable, and DateFormat.format is not thread-safe, this will cause problems if more than one thread tried to log at the same time. Solution: remove the dateFormatter instance variable and instantiate a new DateFormat each time in the log method, e.g. DateFormat dateFormatter = null; try { dateFormatter = new SimpleDateFormat(dateTimeFormat); } catch(IllegalArgumentException e) { dateFormatter = new SimpleDateFormat(DEFAULT_DATE_TIME_FORMAT); } Is anyone available who could make this change?
