Review Comment:
Hello. I am currently reviewing the issue.
At the time of submitting the PR, the following trigger files were used, but
it seems that `PortableRunner` was not included, which is likely why the issue
was not detected:
- `beam_PostCommit_Java_ValidatesRunner_Spark.json`
- `beam_PostCommit_Java_ValidatesRunner_Spark_Java11.json`
- `beam_PostCommit_Java_ValidatesRunner_SparkStructuredStreaming.json`
I agree with @Amar3tto's suggestion. For now, it seems we need to roll back
the changes related to the `PortableRunner` and revisit the task afterward.
