Login jsp idpui for CAS showing UIInfo from prior SAML2 Relying Party

Please find SP metadata.xml attached, as requested...

From the email thread on users@shibboleth.net:

I ran the same test login scenario against an OOB implementation of IdP3 with CAS protocol enabled; restart jetty, login/logout from a SAML2 SP, try CAS service login. Sorry to report same results. I am including a similar idp-process.log excerpt from this test run.

One point of interest… I wanted to check out the source for the class that is referenced in this log entry:
2015-11-03 10:12:24,760 - DEBUG [net.shibboleth.idp.cas.flow.BuildRelyingPartyContextAction:83] - Setting up RP context for verified relying party http://10.10.18.162:7080/cas-sample/j_spring_cas_security_check
… the source repo has the class BuildRelyingPartyContextAction in a different package, net.shibboleth.idp.cas.flow.impl. Maybe I am not browsing the repo correctly?

Anyway, here is the most recent log excerpt:
