## Other Environment Information

- GitHub Actions hosted Ubuntu 22.04 runner
- Workflow: MatrixOne ALL CI, run 31636329821 (attempt 1)
- Job: Matrixone Standlone CI / e2e BVT Test on Linux/x64(LAUNCH, PESSIMISTIC)
- Failed job: https://github.com/matrixorigin/matrixone/actions/runs/31636329821/job/94247850876

## Actual Behavior

The standalone pessimistic BVT job fails during `actions/setup-java` before
MatrixOne is built or started. The action retries its Temurin 8 archive
download twice, then exits with `socket hang up`.

All subsequent MatrixOne build, service-start, and BVT steps are skipped, so
the job cannot validate the PR.

## Expected Behavior

The CI Java setup should obtain its Temurin 8 dependency reliably, or report a
clearly retriable infrastructure failure without failing the MatrixOne BVT
check before it runs.

## Steps to Reproduce

1. Open the failed job linked above.
2. Inspect `Set up Go And Java`.
3. Observe the Temurin 8 download retries and final `socket hang up` error
before `Build MatrixOne` starts.

## Additional information

The failed dependency URL was:

```text
https://github.com/adoptium/temurin8-binaries/releases/download/jdk8u502-b07/OpenJDK8U-jdk_x64_linux_hotspot_8u502b07.tar.gz
```

Relevant log excerpt:

```text
Downloading Java 8 from ...OpenJDK8U-jdk_x64_linux_hotspot_8u502b07.tar.gz
socket hang up
Waiting 15 seconds before trying again
socket hang up
Error: socket hang up
```

This is independent of PR #27058's database-CLONE changes: no MatrixOne source
was compiled and no BVT case executed before the setup action failed.
