Subject Re: Issue with FacetFields.addFields() throwing ArrayIndexOutOfBoundsException
Date Fri, 17 Jan 2014 22:40:23 GMT
I do have a test that will reproduce.  I'm not adding categories with very
deep hierarchies, I'm adding 129 category paths per document (all docs have
paths with same label) with each path having one value.  All of the values
are completely random and likely unique.  It's basically a worst case test
for our app but the condition has been seen in the field (the error has
been encountered at less than worst case scenario).  The test i have
reproduces it very quickly, Only have to index ~330K docs.
