I've got a user encountering a memory leak in production on windows. We can't reproduce it locally.

What steps would you take to diagnose an issue like this? I've never really delved into hprofs or anything like that. Any time I've ever tried looking into memory issues and discovering where they originate, I've found it very challenging to find the source from tooling, however we have the advantage of using the JVM, so there are bound to be tools for this, right?

lots, there's traditional tools like <https://docs.oracle.com/javase/8/docs/technotes/guides/visualvm/heapdump.html|https://docs.oracle.com/javase/8/docs/technotes/guides/visualvm/heapdump.html> and <https://eclipse.dev/mat/|https://eclipse.dev/mat/> or <https://www.jetbrains.com/help/idea/2021.2/open-an-external-profiling-report.html|https://www.jetbrains.com/help/idea/2021.2/open-an-external-profiling-report.html> built into the IDE or command-line tooling like <https://square.github.io/leakcanary/shark/|https://square.github.io/leakcanary/shark/>
