Remote Debugging and Developer Observability

Outside of the language itself, collections are the most basic building block for Java applications. How do we expose them for debugging?

Debugging Java Collections Framework Issues in Production

Rewriting apps is easy. Doing it while preserving compatibility... That's a bit hard. Doing it live in production. That's the big challenge!

RAM profiling has its strengths and weaknesses. The debugger is the perfect complementary tool that translates obtuse statistics to actionable changes

Memory Debugging and Watch Annotations

We use annotations to denote transactional behavior in modern Spring so we have no code, no failure, no debugging... But is it really?
