Answer
jstack shows threads stuck in loops. Frame the concept in practical terms so you can explain it during interview discussion.
Using 'jstack', one can take a snapshot of all thread stacks, revealing threads that are perpetually in the same line of code, indicative of an infinite loop. This is crucial in scenarios like an order processing system that becomes unresponsive due to a loop consuming CPU resources.
