Weirdly I don't see any more stack trace, let me share what I have in
solr.log:

I’m indexing documents with a vector field using SolrJ (javabin
format),
and indexing works fine. However, after indexing, when I run a kNN
search for a specific vector tied to a certain search term (either
through SolrJ or the Solr Admin page), I get an exception. This only
happens for that particular term as far as I’ve seen, though there
might
be other terms that could trigger it. It’s not an issue with every
search term, but it consistently fails with that one.

Interestingly, if I just index my documents again, this time using
HTTP
POST and JSON, error disappears and my search returns as normal.
Any guesses about why something like this might happen? Could quitting
javabin and falling back to XML writer for indexing help?
