I had some IO problems with my .jar file. Some unexpected zip issues - e.g. corrupted zip. You don't expect this. What user expect is that this jar will play nicely or at least get a decent warning/error. But you don't. It all goes 'smoothly', but at the end nothing is deployed, since nothing can be found. And in the flood of debug messages nobody will ever notice that simple debug message, specially since it has no developer added info at the beginning.
