IDP v3.2.1 issue loading metadata

[Izz Noland]

Please bear with me since I usually only work on SPs, and not IdPs.
So, I've installed and begun configuring Shibboleth IDP3 on a CentOS 7 box in our local datacenter.  I'm pretty much following the training material (which was still v2 when I went a couple of years ago) @ https://spaces.internet2.edu/pages/viewpage.action?pageId=49841792 to get 'started' and then tweak the config for prod use afterwards (SSL, resolvers, etc.).  I'm stuck on trying to load the metadata from InCommon.  I've placed in my metadata-providers.xml file the exact config found at https://spaces.internet2.edu/display/InCFederation/Shibboleth+Metadata+Config related to Shibboleth 3.2.0 (and later).  It's not pulling the metadata and I'm seeing this in the idp-process.log:

I appreciate any insight on this issue.  I'm using java 1.8 (albeit openjdk rather than Oracle), and have increased the heap size for JVM.  That doesn't seem to matter here since it is complaining about xsi:type inside of the MetadataProvider elements.

Thanks in advance.

Cheers!
