Narek Karapetian created SPARK-42803:
----------------------------------------
Summary: 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
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.
