This started as a thread on the user list where someone else put up the same information, but there they said that the Solr and SolrJ versions were 4.3.0. The line numbers in the exception on the user list match up to 4.3.0, and the line numbers here match up to 4.7.0, which is good. In the user list discussion the poster indicated that the production application cannot be changed, but can you set up a testing version and send the request directly to Solr, bypassing the play framework? If you do that and it works, then you'll need to look for help with your play framework code on one of their support venues. They'll need to tell you how to relay the response without changing it. If the request direct to Solr doesn't work, then we can troubleshoot that part of it. The user list is a more appropriate venue.
