CAS log issues

[Menno en Erla Avegaart]

I'm testing 5.1.0-RC2-SNAPSHOT and there are several entries in the log I would like to avoid, but don't know how:

1. I'm using a JPA ticket registry and it is configured correctly (I see tickets in the SERVICETICKET and TICKETGRANTINGTICKET tables). So why am I still getting the following warning?

WARN [org.apereo.cas.ticket.registry.DefaultTicketRegistry] - <Runtime memory is used as the persistence storage for retrieving and managing tickets. Tickets that are issued during runtime will be LOST upon container restarts. This MAY impact SSO functionality.>

2. If I start CAS with the embedded Tomcat, then I get the following warning for every file in /WEB-INF/lib:

WARN [org.apache.catalina.webresources.Cache] - <Unable to add the resource at [/WEB-INF/lib/...] to the cache because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache>

I see no reason for Tomcat to cache /WEB-INF/lib, so how do I configure it to skip /WEB-INF/lib?
