------------------------------------------------------------
[~dongjoon] [~hyukjin.kwon] [~xkrogen] [~iemejia]I've been doing some test work
recently:
* Scala 2.13 and JDK 17-ea are easier to use together. We can pass most UTs by
adding some ` --add-opens' rules, maybe we can add these args as default for
`spark.driver.extraJavaOptions` and `spark.executor.extraJavaOptions` when use
JDK 17
* Scala 2.12 doesn't seem to fit well because there are some interfaces
mismatch when using the reflection API with JDK 17-ea
