Thread:Talk:Main Page/Running Error - Robot is not stopping, forcing a stop

Lavenderwong:

When I start the battlefield,my robot and other enemy are frozen. The println messages are not displayed in the robot console. But the command prompt shows the following error. I check that the cause of error is the addition of node in my queue (queue.add(n)). However, this line of code shall be fine i guess. So I would like to ask how to solve this error message?
(this part of my program is for path finding using bfs)

Thank you.
