> 7.7 changed the object type of string field values that are passed to
> UpdateRequestProcessor implementations from java.lang.String to
> ByteArrayUtf8CharSequence. SOLR-12992 was mentioned on solr-user as cause.
> The LangDetectLanguageIdentifierUpdateProcessor still expects String values,
> does not work for CharSequences, and logs warnings instead. For example:
> {noformat}
> 2019-02-14 13:14:47.537 WARN (qtp802600647-19) [ x:studio]
> o.a.s.u.p.LangDetectLanguageIdentifierUpdateProcessor Field name_tokenized
> not a String value, not including in detection
> {noformat}
> I'm not sure, but there could be further places where the changed type for
> string values needs to be handled. (Our custom UpdateRequestProcessor are
> broken as well since 7.7 and it would be great to have a proper upgrade note
> as part of the release notes)
