Supercharge your Java Applications with Python!
summary
Demonstrates embedding Python into Java using GraalPy as two Maven dependencies, plus Gradle/Maven plugins that bundle pip packages into the jar; builds a Micronaut sentiment endpoint wired to VaderSentiment (no Python source files) and a QR-code generator via the Python QR library, both working in-process. Shows debugging with DAP, image processing via Photon via WASM called through a JS wrapper (≈130 req/s, ~60 ms round‑trip, WASM inner ~15 ms), and performance fixes using Apache Arrow to cut a copy-bound job from about 12 minutes to ~30 seconds.
