So the real error is authentication, (the version is spurious) but why that when authentication is being set on the updateRequest?

The only time I would be worried about different SolrJ and Solr versions is when using the CloudSolrClient object. For the other client types, you can usually have a VERY wide version spread without problems. For the cloud object, you *might* have problems with different versions, or it might work fine. If the SolrJ version is higher than the Solr version, the cloud client tends to work. I would always recommend that the client version be the same or higher than the server version... but with non-cloud clients, it won't matter very much. I would not expect problems with the two versions you have, as long as you don't try to use the cloud client. This error is different. It's happening because SolrJ is expecting a Javabin response, but it is getting an HTML error response instead, with the "require authentication" error. This logging message will happen anytime SolrJ gets an error response instead of a "real" response. What this error says is technically correct, but very confusing to novice users. The specific numbers in the message are a result of the first character of the response. With javabin, the first character would be 0x02 to indicate the javabin version of 2, but with HTML, the first character is the opening angle bracket, or character number 60 (0x3C). This is where those two numbers come from.
