A DESCRIPTION OF THE PROBLEM :
java.lang.InternalError instead of Exception

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
import java.io.*;
import java.applet.*;
import java.awt.*;

public class ReadString extends Applet{
public static void crash() {
byte[] b = new byte[2];
b[0]=(byte)0xff;
b[1]=(byte)0xfe;
ByteArrayInputStream bais = new ByteArrayInputStream(b);
String s;
InputStreamReader isr= null;
try{
isr = new InputStreamReader(bais,"Unicode");
}
catch (java.io.UnsupportedEncodingException e) { e.printStackTrace(); }

BufferedReader in = new BufferedReader( isr );

try {
while ( (s = in.readLine()) != null ) { System.out.println( s );}
}

catch (java.io.IOException e) { e.printStackTrace(); }



}

public void paint(Graphics g) {
crash();
}
public static void main(String[] a) {
crash();

}
}
