No its not regularly, I think just once in at least 10 years, probably longer. And it could easily be either a Spring bug, or bad configuration through misunderstanding.

My point was more that it can be opaque when it doesn't act as expected. Sometimes heap inspection is helpful, but if you use Kafka or Spring Data, etc, it can easily just appear to be a char or int array.

So you hit this bug about one and a half times in your entire career, you're not sure Java caused it or even if it was really a bug, but due to it you have a love/hate relationship and garbage collection is terrible?
