Quarkus to load 3rd party properties file from classpath

I'm using a 3rd party library (org.expressme.JOpenId:1.08) that loads some properties file during init:

input = getClass().getClassLoader().getResourceAsStream("openid-providers.properties");

Native compilation works, but the app throws an exception at runtime:

java.lang.NullPointerException: inStream parameter is null

2021-07-29T18:35:18.827814580Z at org.expressme.openid.OpenIdManager.<init>(OpenIdManager.java:28)

How do I fix the problem?

Solution

  • You need to make GraalVM aware of that resource. As mentioned here, you can add something like:

    quarkus.native.resources.includes=openid-providers.properties

    in your application.properties file
