Hi
recently upgraded tomcat to 9.0.71 from 9.0.70
but saw 404 in our EKS cluster(with istio installed)
Received [GET /actuator HTTP/1.1
Host: xxxxx:8079
User-Agent: kube-probe/1.23+
Accept: */*
Connection: close
Accept-Encoding: gzip
]
Incoming request /health with originalRemoteAddr xxxx
in 9.0.70 I can see the below following message but not in 9.0.71
o.a.c.authenticator.AuthenticatorBase : Security checking request GET
/health
seems the processing has stopped somewhere and the pod health check
didn't
pass.
I also noticed there was also a 404 issue but don't know if it is
relevant.

I have tested it locally with curl or jmeter, but can't reproduce
the problem.
but when I step by step debug the spring app, I found the undecodedURI
type
is T_STR
in CoyoteAdapter.java(in 70 it supposed to be T_BYTES), then
decodedURI is
uninitialized and the uri can't find the mapping in internalMap of
Mapper.java, which will cause 404(guess it thinks the uri is malformed)
MessageBytes decodedURI = req.decodedURI();
if (undecodedURI.getType() == MessageBytes.T_BYTES) {
// Copy the raw URI to the decodedURI
decodedURI.duplicate(undecodedURI);
404 example: (when I debug step by step to check unndecodedURI)
curl http://localhost:8080/actuator

However, it runs well without breakpoint! I am quite confused...my
intellij
has problem?
but anyway, summary:
9.0.69 and 70 are good in the AWS/EKS(kubernetes) cluster with istio
9.0.71 and 72 return 404 when health check by the EKS cluster.
Looks like an instance of:

If not that then maybe
