   In 3.4.0 the jsonValue() was callable from Java, and the Javadoc did not 
indicate it was unstable or unavailable.
   
   In 3.4.1 it fails at runtime with a method not found exception, as far as I 
can tell due to this change. This is despite the 3.4.1 javadocs still listing 
its presence.
   
   However, after comparing the Spark 3.4.1 changelog 
(https://spark.apache.org/releases/spark-release-3-4-1.html) to databricks' 
version of the Spark 3.4.1 changelog 
(https://docs.databricks.com/en/release-notes/runtime/13.3lts.html#apache-spark)
 it seems that they've included more patches than upstream? In particular, they 
seem to have pulled this patch into their distribution of 3.4.1, but not the 
later patch that puts the method back. So it might actually be databricks 
mangling the artifact, I'll follow up with them before getting back if they say 
it's upstream spark.
