Looks like this is the issue:
https://bz.apache.org/bugzilla/show_bug.cgi?id=66488
That you only see the problem when using the SSO layer is consistent
with our understanding of that bug.

Are there any known regressions / open issues with 9.0.70 or 9.0.71

The closest I can think of is this:
https://bz.apache.org/bugzilla/show_bug.cgi?id=66388
but it is fixed in 9.0.71 and I'd expect it to impact resource lookup
(i.e.finding files on disk) but not the request URI since the URL class
isn't used got processing the request URI.
It would be good to track this down ASAP as we are about to start the
next round of releases.

We encountered a very odd issue today, where after upgrading the
version of spring-boot for one of our rest microservices (and getting
a newer tomcat) it stopped processing our calls properly.
But only when it was deployed in an env where the requests were going
thru a SSO authentication layer first, and having a number of extra
headers added to the request.
When we tested locally, in an env without the SSO filtering, we didn't
see the issue.
It was a very odd problem, it presented to the end user as simply
getting 404 errors back from the service.
Tomcat was indeed sending 404 errors - but our integrated monitoring
(datadog) was not even showing us the proper requests coming in -
instead, each request that arrived came across with some partial
(random) URL, which then didn't match any of our services, and was
sent back as a 404.
We haven't yet done any further debugging about where in the tomcat
stack the request was being completely corrupted. I also haven't
isolated if it was 9.0.71 or 9.0.70 - 9.0.69 works, and 9.0.71 fails.
Thanks,
Dan
