Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

This section details on the original issue you should resolve

<issue_title>[FEAT]: Make it so the run-smoke-test workflow has added coverage to run the smoke test on Java 25</issue_title>
<issue_description>### Describe the need

Consider .github/workflows/run-smoke-test.yml.

This workflow imperatively causes the smoke test specified in .github/workflows/run-smoke-test.yml to be run, with several, ✅✅extremely important✅✅ overrides so that the test is appropriate in the context of a CI/CD test.

The assignee of this issue must make an additive change to .github/workflows/run-smoke-test.yml so that the JDK 25 Virtual Thread specific behavior is also smoke tested.

Here are some invariant high level guides to the assginee.

1. Existing job smoke-test must be renamed smoke-test-jdk-17.

2. Create a net-new job, smoke-test-jdk-25.

   1. This job is largely a copy/paste of smoke-test-jdk-17 but with the following changes.

      • Run with the Microsoft JDK 25. ❌❌NOT temurin❌❌.

      • Extremely important ✅✅additional✅✅ Critical override statements.

        • Tell the agent to heed the "comment/uncomment" instructions in the Quick Start section of the top level README that have the literal prefix "// JDK 25+:"

          • These changes will make the resultant CopilotSDK class exercise the Java 25 Virtual Thread code path.

        • Make it so these comment/uncomment changes happen before building the jar whose main is CopilotSDK.

The topic branch name for this work must include the issue number for this issue.

@copilot work started on this PR, but I observe this message, "The job was not acquired by a runner even after multiple attempts." . I reverted some commits I suspect are related to this problem.

Please try again. Make sure to get the HEAD of main before resuming work.

Pull request overview

Updates the reusable run-smoke-test GitHub Actions workflow to run the repository’s Copilot CLI–driven smoke test under multiple JDK versions, including a new JDK 25 run intended to exercise the JDK 25 virtual-thread code path described in the README Quick Start.

Changes:

• Renames the existing smoke test job to indicate it runs on JDK 17.
• Adds a second smoke test job targeting Microsoft JDK 25 with additional prompt overrides to enable virtual threads and compile with source/target 25.

.github/workflows/run-smoke-test.yml:65

• New job id does not match the issue requirement. The issue asks for a net-new job named smoke-test-jdk-25, but this workflow defines smoke-test-java25. Please rename the job id to smoke-test-jdk-25 (and keep naming consistent with the JDK 17 job).

    smoke-test-java25:
        name: Build SDK and run smoke test (JDK 25)
        runs-on: ubuntu-latest

[Copilot]

Job id does not match the issue requirement. The issue specifies renaming the existing job to smoke-test-jdk-17, but this workflow defines smoke-test-jdk17 (missing the - before 17). Please rename the job id to exactly smoke-test-jdk-17 to align with the requested invariant naming.
