---------------------------------------------------------------

I have some general doubts
if we see the Lucene change log, we have this change 
[https://github.com/apache/lucene/pull/11998]
in this change, they have marked the below functions as deprecated (they are 
abstract functions)
 * IndexReader.document()
 * IndexReader.getTermVector()

and added the below functions

 * IndexReader.storedFields()
 * IndexReader.termVectors()

if a solr class is inheriting IndexReader class, what should I do as part of 
this upgrade?
should I just change the usage of these deprecated functions to new functions 
or should I delete the overriding functions themselves?
