  3. This is such a clear step-by-step guide. I remember struggling the first time I had to capture a thread dump, and knowing the exact jps + jstack commands would have saved me a lot of trial and error. It reminds me of how simple tooling choices can make debugging on AWS pipelines much easier too.

  4. Clear and practical explanation—thank you! I remember struggling the first time I had to capture a thread dump in production, and these step-by-step commands would have saved me time. It’s interesting to compare this approach with monitoring on an AWS server, where some built-in tools reduce the need for manual dumps.
