Im trying to upload my script from my laptop to my NXT Bot. Connectinng to NXT using wire. When I press the Run as NXT button i get the following error:



js.tinyvm.TinyVMException: Invalid byte tag in constant pool: 15

 ....  

Caused by: org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15

Linking the file failed with exit status 1


I looked at similar problems but they had a problem with queing which my code does not use. Code I'm using:



  public class move {



   public static void main() {



   Motor.B.setSpeed(300);

   Motor.A.setSpeed(720);// 2 RPM

   Motor.C.setSpeed(720);





   Motor.A.forward();

   Motor.C.forward();

   Motor.B.rotateTo(90);

   Delay.msDelay(1000);

   Motor.A.stop();

   Motor.C.stop();

   Motor.B.rotateTo(-90);

   Delay.msDelay(1000);

   Motor.A.rotate( 90);

   Motor.C.rotate(90);





 }



}

                    Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

                    Image
                    up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title.
