> From pac4j github pull request - https://github.com/pac4j/pac4j/pull/445:
> "xmltooling is a part of OpenSAML v2, and is incompatible with OpenSAML v3 (see: https://issues.shibboleth.net/jira/browse/OSJ-152). It appears that it worked fine for most users in the demo projects, because the classloader order happened to place xmltooling after the other opensaml libraries (such as opensaml-core), causing the correct default-config.xml to be loaded, instead of the xmltooling version of the same file.
> The xmltooling library is only used in the pac4j-saml module for a convenience method, which is also implemented in the OpenSAML v3 java-tooling library. This change replaces the call with that newer method, and also removes the xmltooling dependency from the pom.
> This change resolves #444."
> From KnoxSSO testing with Ambari 2.2 on centos 6.4:
