I am trying to get HTTPS/TLS enabled for Tomacat (8.x) preferring the OpenSSL alternative because the cert/key configuration is simpler (compared to the usual JSSE with keystore).
Followed the offical documentation and enabled the connector section like this:
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" sslImplementationName="org.apache.tomcat.util.net.openssl.OpenSSLImplementation" maxThreads="150" SSLEnabled="true" scheme="https" secure="true"><SSLHostConfig protocols="TLSv1.2"><Certificate certificateKeyFile="conf/MyKey.key" certificateFile="conf/MyCertificate.crt" type="RSA" /></SSLHostConfig></Connector>NOTE that I am still using Http11NioProtocol and not APR Http11AprProtocol connector.
However, startup fails with this configuration as this combination of configuration seems to require Tomcat native libraries to be built and configured:

Point is, shouldn't APR/native libraries be only required if I am using Http11AprProtocol which I am not using? What am I missing? Any pointers/help will be much appreciated. Thanks!
