Problem with Apache Tomcat in IdP

[Rod Widdowson]

I'd start by fixing this:

> java.net.UnknownHostException: ds.fedexpresso.edu.br

It looks like you are configured to pull metadata from there but the IdP
cannot resolve that address in DNS.

Then it looks like the cached metadata file has been corrupted or possibly
truncated, or the IdP failed as it was writing it.

But start with your DNS issues.
