The program I am running is as follows, and it crashes at the reader.readNextEvent() line.  

....

public class PlotQ2 {

public static void main(String arg[]) throws IOException{

String s = arg[0];

LCReader reader = LCFactory.getInstance().createLCReader();

reader.open(s);

LCEvent event = reader.readNextEvent();

...

}
