Are there any known regressions / open issues with 9.0.70 or 9.0.71 that could cause
something like the below?
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
