Nightly CI failed on 2026-09-20

[github-actions]

The nightly CI run against main at 1c25b49 did not pass: https://github.com/apache/datafusion-comet/actions/runs/35494125457

Jobs that did not succeed:

• Spark SQL Tests (Spark 4.0) / Build Native + JVM Test Classes (failure)
• Required Checks (failure)

The nightly tier runs the Spark and Iceberg versions the merge queue does not
(see POLICY in dev/ci/compute-changes.py). Close this issue once the failure
is understood; the next red nightly opens a new one.
