I removed the net.shibboleth.idp.plugin.oidc.op and<br>
net.shibboleth.idp.plugin.oidc.config plugins and associated<br>
configuration and the problem went away <shrug>.<br>
<br>
Now I guess I need to narrow down what part of my config for that is<br>
causing it, I assume other people are using the plugins themselves with<br>
5.2 without issues.<br>
