Github user kiszk commented on the issue:

    https://github.com/apache/spark/pull/15840
  
    Does this approach avoid to generate code `convertedArray[loopIndex] = null;` if `lambdaFunction.nullable`
is `true`? Is it a design? I know that it works correctly in this case since an array allocation
ensures that all of the elements have `null`.
    
    I am curious that whether the current restriction (generate only if-then) in `nullSafeExec()`
works in other places.
