beliefer opened a new issue, #10559:
URL: https://github.com/apache/incubator-gluten/issues/10559
### Description
The implementation of StrictRule used to replaces the children with
`DummyLeafExec` s so they become inaccessible afterward.
But there exists a conflict that `LegacyOffload` applies each rule with
`transformUp`.
```
class LegacyOffload(rules: Seq[OffloadSingleNode]) extends Rule[SparkPlan]
with LogLevelUtil {
def apply(plan: SparkPlan): SparkPlan = {
val out =
rules.foldLeft(plan)((p, rule) => p.transformUp { case p =>
rule.offload(p) })
out
}
}
```
In other words, the class `DummyLeafExec` is invalid due to the mechanism of
`transformUp`.
