UBI system CA certificates not loaded

[faandg]

We want to use an on-premise maven repository to install features instead of using the public one. It has a company signed cert so we need to establish trust with it by importing the company CA.

Is there a way to load /etc/pki/ca-trust/extracted/java/cacerts to use in features.sh?
The script seems to call the java binary directly so I expected it to work out of the box on an UBI image.
I think the Red Hat build of OpenJDK does load it by default which is why I originally opened an issue in the Semeru Runtimes Github but I'm not getting any response there.
