maschmid@redhat.com reported ~~JWS-1397~~ with Tomcat on OpenShift, although the issue is not specific to OpenShift.
Follows a dead simple reproducer for local usage, independent of OpenShift/Docker:

Reproducer on JWS 5.1, Tomcat 9.0.7, tcnative 1.2.17, OpenJDK 1.8.0.212.b04-3.el8.x86_64

Fetch and unzip Tomcat
Fetch and unzip Jolokia
Fetch ca.cert.crt

Prepare jolokia.properties e.g. as in

host=127.0.0.1
port=8778
discoveryEnabled=false
user=jolokia
password=1dyar6DPuP65QYOu2hYXtZ3kunUcbr
protocol=https
useSslClientAuthentication=true
extraClientCheck=true
caCert=/opt/noe-tests/resources/ssl/proper/generated/ca/certs/ca.cert.crt

In your Tomcat's bin/ directory:
export CATALINA_OPTS="-Djava.security.egd=file:/dev/./urandom -javaagent:/home/karm/JWS/jolokia-1.6.1/agents/jolokia-jvm.jar=config=/home/karm/JWS/jolokia.properties"

Use e.g. one-liner such as:

while [ 1 ];do sleep 1;pkill -TERM java;./catalina.sh start > /dev/null;
   until $(curl --silent --output /dev/null --fail --head http://127.0.0.1:8080/);do echo -e ".\c";sleep 0.5;done;echo OK;
   ./catalina.sh stop  > /dev/null;done;

Output could be as:

..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..OK
..............................................................

When the many dots appear, the Tomcat is stuck.

I couldn't reproduce it with Tomcat 9.0.20 / tcnative 1.2.17. That matches with Mark's note:
