Summary: dr. java error when writing a class

Initial Comment:
I was writing the class below in Dr. Java, and I think that the cursor was somewhere between the bottom two curly brackets, and I pressed enter, and it caused the Dr. Java error shown below the class. I copied the class, closed Dr. Java, reopened it, pasted the copied class into the window, then pressed enter again somewhere between the same two brackets, and I got the same error again. My version is drjava-20090821-r5004. I use JDK 6.0_4. I have windows xp, media center edition, version 2002, service pack 3.

public class ArrayStack<E> implements Stack<E> {

  private E[] elements;
  private int top;

  public ArrayStack(int capacity) {
    elements = (E[]) new Object[capacity];
    top = 0;
  }

  public void push(E element) {
    if(
  }

}
