> Use getParameterCount function instead of getParameterTypes.length
> ------------------------------------------------------------------
>
> Key: SPARK-42803
> URL: https://issues.apache.org/jira/browse/SPARK-42803
> Project: Spark
> Issue Type: Improvement
> Components: ML, Spark Core, SQL
> Affects Versions: 3.3.3
> Reporter: Narek Karapetian
> Priority: Minor
> Fix For: 3.3.2
>
>
> Since jdk1.8 there is an additional function in reflection API
> {{{}getParameterCount{}}}, it is better to use that function instead of
> {{getParameterTypes.length}} because {{getParameterTypes}} function makes a
> copy of the parameter types array every invocation.
> This will help to avoid redundant arrays creation.
