UnsupportedClassVersionError when installing DuoOIDCNimbusPlugin with OpenJDK11

[Max Spicer]

Thanks, Scott, I missed that. I also got confused about which version of
the IdP I was running as I'm currently testing an upgrade to 4.3.1 and am
doing this exploration on a dev box. I was actually running 4.2.1.

Looking at
https://shibboleth.net/downloads/identity-provider/plugins/plugins.properties,
there isn't actually a current version of the DuoOIDC plugin that supports
IdP 4.2.1. I did have it in my head that DuoOIDC was a(nother) reason to
upgrade to 4.3 but then couldn't find this spelled out explicitly when I
looked at this again. Looking at plugins.properties, the latest versions
that support 4.2.1 are duo-oidc 1.3.0 and oidc-common 2.1.0. These versions
do indeed install without errors.

This is my first use of DuoOIDC and indeed of the plugin system. 4.3.1
seems to be the way to go.
