> There is a string comparison "sCopy != e.getKey()" with a != and not an
> equals. It basically never works right. Not sure if someone was trying to
> be clever but even if those strings are the same they happen to be
> different objects. Which I'm assuming is due to how the strings are
> serialized in from the config files.
> Suggest its updated to
> String sCopy = solrMapping.mapCopyKey(e.getKey());
> if (!sCopy.equals(solrMapping.mapKey(e.getKey()))) {
>        inputDoc.addField(sCopy, val2);
