Newer versions of SolrJ utilize the Jetty httpclient for http/2 support, not the apache httpclient. The older client, using apache httpclient 4.x, is still present in newer SolrJ versions. Your message did not indicate which version of SolrJ you are using. One of your previous emails to the list mentions version 8.6.3 of SolrJ ... the httpclient 4.x jars that you have are different versions than that version of SolrJ asks for. Looking over previous emails that you have sent to the mailing list, I wonder why you are adding jars manually instead of letting Maven handle all of the dependencies. A common problem when dependency resolution is not automatic is that the classpath is missing one or more of the jars that exist on the filesystem. I don't think this problem is directly caused by SolrJ. It could be that the httpclient 4.x jars you have are not new enough, or there might be some unknown interaction between the 4.x jars and the 5.x jars. Or maybe your classpath is incomplete -- doesn't include something in your file listing above. Problems like this can also be caused by having multiple copies of the same or similar versions of jars on the classpath. That kind of issue could be very hard to track down. It can easily be caused by utilizing a mixture of automatic and manual dependencies. Choose either all automatic (maven, ivy, gradle, etc) or all manual. Thanks, Shawn
