I started a thread last week about running solrj using Solr 8.5.1. My program was crashing. I was using it with Nutch 1.16. In the documentation, it was recommended that Nutch 1.17 be used with Solr 8.5.1. Nutch 1.17 is still a developer version and not released, so I have downloaded Solar 7.3.1 to use with Nutch 1.16.
I have been able to build up a small index in Solr using Nutch and I can see the Solr core containing the index in the solr admin window.
Next, I tried to query Solr using solrj, using an example I found at:
I wrote my own version of the example and tried running it and I get the following
This problem occurs on a linux platform, and the output from 'uname -a' is:
Linux roe 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u2 (2017-03-07) x86_64 GNU/Linux
I have logged my steps and can probably reproduce the problem, but it does take some time. Along the way I had some warnings and potential error messages (I too new to Solr to know if the messages were errors or not) so the crash could be due to bad data in the index.
