This I would consider a bug.
Probably the easiest approach to stream data from the /export handler with
Solrj is to use a SolrStream to send a Streaming Expression that reads from
the export handler. This blog describes the approach:

J
Solr version is 8.4
I'm trying to use the export handler through SolrJ:
CloudSolrClient cloudSolrClient = ...
SolrQuery q = new SolrQuery();
q.setParam("q", "ts:[1612368422911 TO 1612370422911]");
q.setParam("sort", "ts asc");
q.setParam("fl", "ts");
q.setRequestHandler("/export");
cloudSolrCli
