Ah ok, that's a little clearer then. Here's the full stack trace:

Our auditors actually raised the issue with us, claiming it is a vulnerability

Renegotiation is supplied.

Are you sure there is a vulnerability here you need to avoid? What version of
APR/native are you using? What version of OpenSSL is it built with? I'd expect
just using the latest version would protect against this.

OK. You are definitely protected against client initiated renegotiations.
A later version of Tomcat would tell you the OpenSSL version as well.

Loading the APR library does not mean that it will be used for a connector. The
logs will tell you which connector is being used once you get past the CNFE
problem.
Is there some more to that stack trace? It looks like the protocol attribute in
server.xml isn't the one you quoted but there might be something else going on
- that is why the full stack trace would be helpful.
