December 2025 — Eclipse OpenJ9 (openj9) CI cleanup stabilization: delivered a targeted bug fix to make workspace cleanup robust when job paths contain spaces. The patch quotes paths in get_other_workspaces to prevent 'No such file or directory' errors during node cleanup, reducing intermittent CI cleanup failures in multi-node builds. This is a low-risk, compatible change that improves build reliability and throughput without altering public interfaces.
