Fails to build with JDK 17

Describe the Bug

Fails to build when attempting to run the build with JDK 17. Based on the error message it looks like this is a check in project.clj but I don't know if this is simply a matter of enabling support for version 17 or if code changes will be required. I tried to see if there was an overall plan for support for newer JDKs but didn't find anything.

The error message is as follows:

$ lein
OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

Expected Behavior

Since JDK 17 now is the current LTS version of Java, I would expect to be able to build and run this and other repositories with it.

Steps to Reproduce

Steps to reproduce the behavior:

Install and set JDK 17 as the default Java version on your system
Run lein in the root directory.

Environment

Version: latest main
Platform: Debian Sid
JDK: OpenJDK 17.0.5

Additional Context

I've seen similar errors on at least https://github.com/puppetlabs/trapperkeeper-metrics https://github.com/puppetlabs/trapperkeeper-webserver-jetty9 Since those repos contain the same version number check, I would assume other clojure repos may also be affected.
