  1. JVM Runtime Data Areashistorical

    Heap, stacks, method-area metadata, program counters, native stacks, and the difference between JVM specification concepts and HotSpot implementation details.

  2. JVM Object Allocationhistorical

    How HotSpot commonly allocates objects, including TLABs, young-generation allocation, large objects, promotion, and why exact rules depend on the collector.

  3. Escape Analysishistorical

    JIT escape analysis, scalar replacement, lock elimination, and why stack allocation should not be treated as a guaranteed Java object-allocation rule.
