In the HotSpot JVM, this is the job of the just-in-time compilers C1 and C2 and between speculation and traps, inlining and constant folding, escape analysis and scalar replacement (and many more), they apply a number of heuristics, analyses, and transformations to achieve that. This requires expertise, careful research, thorough testing, and regular reevaluations of old assumptions. In this &quot;Ask the Architects&quot; episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Roberto Lozano, compiler engineer at the Java Platform Group at Oracle. In our show &quot;Ask the Architects&quot;, we talk to experts in OpenJDK about their work on the Java language, API, and runtime.
