This will keep looping even if the thread gets interrupted. That's not expected, right?

You can put the try-catch outside the while loop, and update the while condition as

while (!Thread.currentThread().isInterrupted()

I'm stopping this thread via the close function. The print statement is misleading. Will fix it and add a break after that as well.

Thanks for your suggestion, I'll make some changes around it for better readability.
