'Getting class not found spark/internal/logging$class
I am trying to understand the logging.scala code for spark_2.11_v_2.4.1 and spark_2.12_v_3.1.2. When I am trying to check at the decompiled files for the two, I am seeing multiple classes created in the interface in the JD.

I am trying to understand how these classes are coming here and why is it not coming in spark 3.1.2 Is it because of any change in the spark logging code or because of Java decompiler? I have an application where I have placed spark 3.2 and it is throwing error for spark/internal/Logging$class. I am relatively new to spark and scala.
