Is this program supposed to throw an error?I passed the validation but my program threw a NoSuchObjectException. This is because we are "pretending" that we made a server and client, right?

Question about the task Tracking changes
Java Core, Level 9, Lesson 11
Under discussion
Can't even get code to run Doesn't even get out of the for loop. I've never seen this before. All that's being done is two ArrayLists are being compared and iterated. Doesn't make any sense to me that the for loop doesn't break. Spent 2 days trying to figure this out. I really just want to move on. Please explain this to me!
