Review Comment:
Also, I'm observing this test case failure still in some environments
although this PR claims that `These tests will not fail after this PR`.
> Also, some existing tests will fail when the config
ARTIFACTS_SESSION_ISOLATION_ALWAYS_APPLY_CLASSLOADER is enabled:
> AdaptiveQueryExecSuite: SPARK-37753: Inhibit broadcast in left outer join
when there are many empty partitions on outer/left side
> DatasetOptimizationSuite: SPARK-27871: Dataset encoder should benefit from
codegen cache
> These tests will not fail after this PR.
