snuyanzin opened a new pull request, #28284:
URL: https://github.com/apache/flink/pull/28284
## What is the purpose of the change
This is a preliminary change before bumping Calcite to 1.39.0
The main reason here is that this class is relatively often a problem while
Calcite upgrade if something is changed in interfaces (new default methods for
instance)
maven just fails as
```
[ERROR] error: Error while emitting FlinkTypeFactory.scala
[ERROR] assertion failed:
