> Many thanks to @TobiHartmann for the speedy investigation. This patch fixes the issue by adding a `ciField` for the null marker. I also do a small change to make the name of the `ciField` of a flattened field clearer. I think adding a scenario to test flattening of nullable and atomic fields is necessary. There are some failures that I filed https://bugs.openjdk.org/browse/JDK-8357061 for the investigation.
