Eclipse hangs when attempting to step into function

Eclipse freezes when I tried running the following code in debug mode:

public class LinkedListTest2 {
    public static void main(String[] args) {
        Node a = new Node(1);  // Attach breakpoint here
        Node b = new Node(2);
        Node c = new Node(3);
        
        a.next = b;
        b.next = c;
        c.next = null;
        
        System.out.println(toString(a));  // Step into here
    }
    
    public static String toString(Node head) {
        StringBuilder builder = new StringBuilder();
        while (head != null) {
            builder.append(head.data);
            if (head.next != null) {
                builder.append(", ");
            }
            head = head.next;
        }
        return "[" + builder.toString() + "]";
    }
    
    public static class Node {
        public int data;
        public Node next;
        
        public Node(int data, Node next) {
            this.data = data;
            this.next = next;
        }
        
        public Node(int data) {
            this(data, null);
        }
    }
}

To reproduce:

1. Attach a breakpoint to line 3 and start debug mode.
2. Press the "step over" button several times until you are highlighting the println on line 11
3. Once you are on line 11, press the "step into" button to try and step into the "toString" function
4. Eclipse will freeze instead of stepping into the function

It's unclear to me exactly why this is happening, but I did find that reducing the number of nodes in the main method to 1 or 2 made the error go away.
