Description

A request such as:

/select?version=2.2&q=%3A&fq=%3A&start=1&rows=2147483647&fl=uri

causes an AIOOBE. This happens when rows is MAX_INT or MAX_INT-1 (I suspect anything greater than MAX_INT-start-1). It happens with both XML and BinaryResponseWriter. Doesn't seem to happen with embedded solr.

I don't know whether this may have been fixed since 3.4 - sorry, but I thought it was better to report than not to report it, even so.

Here's a typical stack trace:
