Nope, I also tested it with NIO instead of APR, same issues happen. RewriteValve does not function as expected. Besides it, there are also two https-443-exec executed by one request.
There is definitely something wrong with Http2Protocol. And it results in this case a problem in RewriteValve. And what kind of extra information do you want to have. I cannot send any pictures in the email. You want the server.xml configuration? Except that file, almost every other configuration file is untouched. No load balancer, no any proxy here. Just a straight forward connection to tomcat instance. Here an remark, you can only reproduce errors if Http2Protocol is indeed activated, namely you see in browser h2 protocol is used by request. In Eclipse, I cannot reproduce the issue, since I cannot get h2 protocol working there.
