/**
* Do a best effort to clean up all resources allocated when populating

* closed automatically by the index writer once it's done with them, but
* we may not get that far if something fails.

* @param doc the document whose resources to clean up

// If the field takes input from a reader, close the reader.

// If the field takes input from a token stream, close the
// token stream.
