summary

Series of practical sessions that show how Java teams tackle warmup, AI and secrets rather than theory: JVM warmup options compared (Graal native-image, ReadyNow/cached JIT, cloud JIT, CRIU checkpointing) with measured cold-start wins like 3898ms → 38ms for a Spring Boot restore; generative-AI tooling landscape where Python libraries dominate but Java can use Spring AI, Semantic Kernel, LangChain4J and must manage token costs and prompt patterns; secrets hygiene with managed identities, local Key Vault emulator, import/export and time‑travel for CI; and LangChain4J demos including structured extraction and a car recommender showing LangChain4J mapping to Java types and real hallucination tradeoffs.
