> We recently upgraded from Solr 7.3 to 8.1, and noticed that the maxChars
> property on a copy field is no longer functioning as designed, while indexing
> via SolrJ. Per the most recent documentation it looks like there have been no
> intentional changes as to the functionality of this property, so I assume
> this is a bug.
>
> In debugging the issue, it looks like the bug was caused by SOLR-12992. In
> DocumentBuilder where the maxChar limit is applied, it first checks if the
> value is instanceof String. As of SOLR-12992, string values are now coming in
> as ByteArrayUtf8CharSequence (unless they are above a certain size as defined
> by JavaBinCodec.MAX_UTF8_SZ), so they are failing the instanceof String
> check, and the maxChar truncation is not being applied.
>
> The issue seems to be limited to Javabin, docs indexed in other formats
> (where values come in as strings) are working fine.
