quarkus: Read/use system resources in native mode throwing NPE

Describe the bug I’m trying to read a private key to sign JWT tokens but i get NPE when using system resources in native mode

Expected behavior Read key and sign jwt but also i saw some related issues, assumes it’s resolved when updating to Quarkus 1.5.0.Final but i actually use 1.5.1.Final and still get this in native mode

Actual behavior Got NPE in Native Mode

To Reproduce Steps to reproduce the behavior:

1. mvn package -Pnative
2. execute runner
3. generate token
