If you are seeing this when you start TomCat on a Shibboleth server you need to check your Shibboleth configuration as follows:
13:43:13.007 - WARN [edu.internet2.middleware.shibboleth.common.config.SpringConfigurationUtils:276] - Numerical duration form is deprecated. The property 'maxValidityInterval' on metadata filter of type {urn:mace:shibboleth:2.0:metadata}RequiredValidUntil should use the duration notation: P46DT12H0M0.000S
Open relying-party.xml and change the maxvalidityinterval value within this section to: P46DT12H0M0.000S instead of: 4017600.
