1. find out all the proto classes T which are passing as parameter List<T> ,
2. change ScmListCodec to support generic type, and
3. add a ScmListCodec for each proto class.

Sorry that the idea above does not work well for ScmListCodec.

Could you see if [this 
idea|https://issues.apache.org/jira/secure/attachment/13081236/9919_review.patch]
 would work?

> Implement ScmListCodec without reflection.

> Similar to HDDS-14647, we should
> # find out all the proto classes T which are passing as parameter List<T> ,
> # change ScmListCodec to support generic type, and
> # add a ScmListCodec for each proto class.
> If there are many proto classes required, we may consider adding the codec 
> dynamically, i.e. use reflection or other method to add the codec when it is 
> required the first time.
