From bd7cdbcceeacd37f8ac61a2b65ce346a73f22397 Mon Sep 17 00:00:00 2001 From: Bruno Borges Date: Tue, 26 May 2026 13:04:46 -0400 Subject: [PATCH 1/3] feat: Add automatic JDK 25 virtual thread support and simplify executor handling This commit adds automatic virtual thread support on JDK 25+ via multi-release JAR and eliminates executor null-checking code smell throughout the SDK. **Key Changes:** 1. **Multi-Release JAR Support for Virtual Threads** - Added `DefaultExecutorProvider` with Java 17 base (returns ForkJoinPool.commonPool()) - Added Java 25 multi-release version (returns virtual thread executor) - Updated Maven build to compile Java 25 version into META-INF/versions/25 - Updated workflows to build with JDK 25 for proper multi-release JAR generation 2. **Eliminated Executor Null Checks** - Removed redundant ternary checks in CopilotClient (lines 189, 330) - Simplified constructor logic for executor initialization - Executor field is now guaranteed non-null 3. **Documentation Updates** - Removed manual virtual thread instructions from README quick start - Updated requirements to explain automatic JDK 25+ virtual thread usage - Simplified smoke test workflow (no longer modifies sample code) 4. **Test Coverage** - Added DefaultExecutorProviderTest with multi-release JAR validation - Fixed JaCoCo to exclude multi-release classes from coverage - All 1005 tests pass **Benefits:** - Cleaner, more maintainable code without null checks - Automatic virtual thread adoption on JDK 25+ (no user action required) - Backward compatible with Java 17+ - SDK manages executor lifecycle properly Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .github/workflows/build-test.yml | 2 +- .github/workflows/publish-maven.yml | 5 +- .github/workflows/publish-snapshot.yml | 4 +- .github/workflows/run-smoke-test.yml | 5 +- README.md | 11 +- pom.xml | 46 ++++++++ .../com/github/copilot/sdk/CopilotClient.java | 41 ++++--- .../copilot/sdk/DefaultExecutorProvider.java | 18 +++ .../sdk/json/CopilotClientOptions.java | 21 ++-- .../copilot/sdk/DefaultExecutorProvider.java | 18 +++ src/site/markdown/index.md | 2 +- .../sdk/DefaultExecutorProviderTest.java | 107 ++++++++++++++++++ 12 files changed, 237 insertions(+), 43 deletions(-) create mode 100644 src/main/java/com/github/copilot/sdk/DefaultExecutorProvider.java create mode 100644 src/main/java25/com/github/copilot/sdk/DefaultExecutorProvider.java create mode 100644 src/test/java/com/github/copilot/sdk/DefaultExecutorProviderTest.java diff --git a/.github/workflows/build-test.yml b/.github/workflows/build-test.yml index 29fd1fd119..62a3cd07c7 100644 --- a/.github/workflows/build-test.yml +++ b/.github/workflows/build-test.yml @@ -51,7 +51,7 @@ jobs: node-version: 22 - uses: actions/setup-java@be666c2fcd27ec809703dec50e508c2fdc7f6654 # v5 with: - java-version: "17" + java-version: "25" distribution: "microsoft" cache: "maven" diff --git a/.github/workflows/publish-maven.yml b/.github/workflows/publish-maven.yml index cc612389b7..4eafdff0a6 100644 --- a/.github/workflows/publish-maven.yml +++ b/.github/workflows/publish-maven.yml @@ -50,10 +50,10 @@ jobs: - uses: ./.github/actions/setup-copilot - - name: Set up JDK 17 + - name: Set up JDK 25 uses: actions/setup-java@be666c2fcd27ec809703dec50e508c2fdc7f6654 # v5 with: - java-version: "17" + java-version: "25" distribution: "microsoft" cache: "maven" server-id: central @@ -253,4 +253,3 @@ jobs: -f publish_as_latest=true env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} - diff --git a/.github/workflows/publish-snapshot.yml b/.github/workflows/publish-snapshot.yml index c10af9fd0e..12a6e5ea04 100644 --- a/.github/workflows/publish-snapshot.yml +++ b/.github/workflows/publish-snapshot.yml @@ -26,10 +26,10 @@ jobs: - uses: ./.github/actions/setup-copilot - - name: Set up JDK 17 + - name: Set up JDK 25 uses: actions/setup-java@be666c2fcd27ec809703dec50e508c2fdc7f6654 # v5 with: - java-version: "17" + java-version: "25" distribution: "microsoft" cache: "maven" server-id: central diff --git a/.github/workflows/run-smoke-test.yml b/.github/workflows/run-smoke-test.yml index 8d0feac0c1..9640c13af3 100644 --- a/.github/workflows/run-smoke-test.yml +++ b/.github/workflows/run-smoke-test.yml @@ -94,10 +94,7 @@ jobs: **Critical override — do NOT run the jar:** Stop after the `mvn --no-snapshot-updates clean package` build succeeds.
