I've created a minified JRE using the JLink tool
jlink --add-modules java.base,jdk.crypto.ec --output jre
I've created a very basic application that connects to https://www.example.com
When I run this application using the JDK, everything works fine. When I run this using the minified JRE, I get the following:

I've noticed the lib\security\cacerts file in the JDK is much larger than in the minified JRE (246KB vs 156KB). When I copy this file into the minified JRE, then my application works correctly.
This suggests that the JLink process is removing some of the certificates for some reason. I can't see any explanation in the documentation for this, or online. Am I missing something?
This is a known bug in Corretto.
