See attachment for full stack traces.
There are a few of HTTP and HTTPS connectors with IPv4 and IPv6 addresses.
HTTPS connectors configured like this:
<Connector address="..." port="443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
connectionTimeout="20000"
compression="on"
compressableMimeType="text/html,application/xml,text/css,application/javascript,text/plain,application/json">
<UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
<SSLHostConfig>
<Certificate
certificateFile="..."
certificateKeyFile="..."
certificateChainFile="..."
</SSLHostConfig>
</Connector>
Without <UpgradeProtocol> exceptions do not appear.
Server is running Tomcat 8.5.8 + tcnative 1.2.10 + openSSL 1.0.2h.
I cannot reproduce this on testing server with the same configuration by my own
requests.
