ArrayIndexOutOfBoundsException for a specific vector search

[Ufuk YILMAZ via users]

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.

o.a.s.h.RequestHandlerBase Server exception 
=>java.lang.ArrayIndexOutOfBoundsException: Index 727 out of bounds for 
length 727
        at 
org.apache.lucene.util.FixedBitSet.nextSetBitInRange(FixedBitSet.java:297)

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?
