I searched and there is this article working with randoms native image but I still could not figure out what I need to do to resolve this.
Seems like quarkus tries to create an instance of Random or SplittableRandom for a drools class, I am using optaplanner quarkus and I do not use drools rule engine, I use constraint streams.
Does anyone have the same problem while building native image for optaplanner quarkus application? What should I do to overcome this? I tried graalvm 22.0 and 21.3, both have the same problem.
Thanks for your help in advance.
The following line tells me that there is a problem on your classpath:
Call path from entry point to org.drools.wiring.dynamic.PackageClassLoader.writeClass(String, byte[]):
The drools-wiring-dynamic module is not designed to work in the native mode, and needs to be replaced by drools-wiring-static. In fact, the optaplanner-quarkus module does all this work for you.
Are you using optaplanner-quarkus instead of optaplanner-core? The stack trace tells me you maybe aren't. If you are, I suggest you figure out the source of the drools-wiring-dynamic dependency, and remove it.
One other source of problems may be that you are trying to use constraint DRL in native mode. That is not supported and will fail with one exception or another. In native mode, you have three choices for constraints - Constraint Streams, Java Incremental or Java Easy.
