Review comment:
For this one, we hit many issues at Apache ORC 1.6.x due to the breaking
API and behavior change.
Although this is an implementation internal class, Hive and Spark's hive
module assumes old behavior.
So, if we need this change, I'd like to recommend to have a configuration to
support both behavior.
