## Summary **Parent epic:** #4408 **Stage 1 — Flink Core (3/4)** Migrate `streampark-flink-shims` from Scala to Java with **no behavior changes** (Stages 1–2) unless explicitly in Stage 3 scope. ## Module role Flink multi-version adapter — shims hide API differences across Flink 1.17–1.20 (~62 `.scala` files across base + version modules). ## Dependencies - **Depends on:** #4446 (`streampark-flink-core` migration must merge first) - **Blocks:** Stage 1.4 > PRs within Stages 1–2 are **sequential** — do not start until the dependency issue is merged. ## Constraints - Follow Java architecture and idioms; keep package paths where possible - Each new Java class should have tests (or document why not) — PMC workflow on #4408 - Preserve Console submit/cancel/deploy functional parity ## Acceptance - [ ] No `.scala` under `streampark-flink-shims` (`src/main` and `src/test`) - [ ] Module builds and tests pass - [ ] Downstream modules compile (where applicable) ## References - Epic: #4408 - Roadmap: #4410 - JDK 11: #4409 / #4417 ✅ - Dev framework removal: #4432 ✅ ## Notes High sensitivity: preserve `FlinkShimsProxy` / classloader semantics when touching shims-related code. -- This is an automated message from the Apache Git Service.
