+# Java Application Modernization agent instructions
+
+## Your Role
+- You are a highly sophisticated automated coding agent with expert-level knowledge in Java, popular Java frameworks and techniques of modernizing legacy Java. 
+- Your task is to migrate the Java project to use Java 25, Gradle 9.1.0 and Jersey 2.
+
+## Boundaries
+- **DO** make changes directly to code files.
+- **DO** directly execute your plan and update the progress.
+- **DO NOT** seek approval, user preferences or confirmations before making changes. Proceed with your best judgment with the next actions automatically.
+You DO have the highest decision-making authority at any time.
+
+**Derived Paths**:
+- **Progress File**: `progress.md`
+- **Plan File**: `plan.md`
+- **Summary File**: `summary.md`
+
+## Scope
+* DO - Scan the codebase to analyze deprecated APIs
+* DO - Execute code transformation using tools like OpenRewrite
+* DO - Update Gradle dependencies and resolve dependency coordinates, like incompatible library versions and transitive dependency conflicts
+* DO - Code modification to replace original technology dependencies with equivalents
+* DO - Configuration file updates necessary for compilation
+* DO - Ensure that the integrity of Java classes and methods in maintained post upgrade, and the application features must work seamlessly
+* DO - Fix build errors iteratively
+* DO - Find all relevant candidates where latest Java 25 code features can be applied
+* DO - Propose a safe, testable migration plan
+
+## Success Criteria
+* Codebase compiles successfully
+* Code maintains functional consistency after migration
+* All unit tests pass after migration
+* All dependencies and imports are replaced
+* No CVEs introduced during migration
+* All old code files and project configurations are cleaned
+* All migration tasks are tracked and completed
+* Plan generated, progress tracked, and summary generated, and all the steps are all documented in the progress file

+# Java Application Modernization Plan (Cap-20844)
+
+## Objectives
+- Migrate build/tooling to Java 25 and Gradle 9.1.0.
+- Migrate Jersey 1.x client integration to Jersey 2 (JAX-RS 2) and remove `com.sun.jersey` dependencies/usages.
+- Keep existing behavior (load-balancing filter, host polling, ECS host discovery, tests).
+- Maintain a green build (`gradlew test`).
+
+## Milestones
+1. Tooling upgrade
+   - Gradle wrapper -> 9.1.0
+   - Java toolchain -> 25
+   - Modernize Gradle publishing/config DSL for Gradle 9 compatibility
+2. Jersey migration
+   - Update dependencies to Jersey 2.x equivalents
+   - Refactor Jersey 1 specific code to JAX-RS 2 APIs
+   - Replace Jersey 1 internal providers with portable JAX-RS providers
+3. Verification
+   - Ensure all modules compile
+   - Ensure all unit tests compile and pass
+
+## Risks / Notes
+- Windows file locking during `clean`/archive tasks (mitigated in build logic).
+- Java 25 removes JAXB from the JDK; JAXB dependencies must be explicit.
+- Jersey 2 uses `javax.ws.rs` APIs (not `jakarta.ws.rs` in 2.x).

+# Progress Log
+
+## 2026-02-09
+- Updated Gradle wrapper to 9.1.0 and modernized root `build.gradle` for Gradle 9 / Java 25 toolchains.
+- Updated module dependencies:
+  - `smart-client-jersey`: Jersey 2 client + Apache connector + Jersey JSON/JAXB media modules; explicit `javax.ws.rs-api`.
+  - `smart-client-ecs`: Jersey 2 client; JAXB API/runtime for Java 25; explicit `javax.ws.rs-api`.
+- Refactored Jersey integration code:
+  - `SmartFilter` migrated from Jersey 1 `ClientFilter` to JAX-RS 2 `ClientRequestFilter`/`ClientResponseFilter`.
+  - `SmartClientFactory` migrated to Jersey 2 `ClientBuilder` + `ApacheConnectorProvider`, and registers features/providers.
+  - Replaced Jersey 1 internal providers/utilities:
+    - `SizedInputStreamWriter` now streams directly (no Jersey `ReaderWriter`).
+    - `SizeOverrideWriter` now uses portable `MessageBodyWriter` delegates.
+    - `OctetStreamXmlProvider` now uses JAXB unmarshalling.
+- Refactored ECS integration:
+  - `EcsHostListProvider` migrated from Jersey 1 client API to JAX-RS 2 (`Client.target(...)`, `Invocation.Builder`).
+- Updated tests:
+  - `SmartClientTest` migrated to JAX-RS 2 client API, using Jersey 2 timeout properties and `Response`/`Entity`.
+  - `EcsHostListProviderTest` migrated to JAX-RS 2 client API; uses `SmartClientFactory` for client creation.
+- Verification:
+  - `./gradlew test` succeeded.
+  - Re-ran `./gradlew test` after SmartFilter fix; build remains green.
