    The sole purpose of adding `SpecificMutableRow` is to avoid boxing cost, so using `boxed`
here doesn't sound good. For SPARK-5236, schema mismatch can often produce similar exceptions.
@alexbaretta Would you please add a snippet that helps reproducing this issue in the JIRA
ticket description? I guess the root cause hides elsewhere.
