Q

Bắt đầu tại processing.app.Sketch.setModified trong Sketch.java:760 và lần theo đường dẫn tạo trình soạn thảo của JavaEditor và JavaMode được nêu trong stack trace. Tái hiện lỗi bằng cách mở một sketch thông qua menu trình soạn thảo, sau đó xác định hành vi mong đợi khi current là null và xác minh rằng việc mở không còn ném ra exception này.
