Quarkus Native with Optaplanner fails to start with EasyScoreCalculator #37871
Description
Describe the bug
Our Quarkus/OptaPlanner application works fine in JVM mode, but when compiled to Native executable, it throws a exception at initialization.
versionn (powered by Quarkus 2.16.12.Final)
We attempted to register the class via solverConfig.xml and added the resource refernce in application.properties, but it still did not help.
quarkus.native.resources.includes=solverConfig.xml
We have several services that use streaming constraint API and those are working fine. It's just this one with EasyScoreCalcuator that won't start.
Expected behavior
Solver should start normally.
Actual behavior
2023-12-20T15:18:32.848536120Z Caused by: java.lang.IllegalStateException: If there is no scoreDrl (null), scoreDrlFile (null) or constraintProviderClass (null) with DROOLS impl type (null), there can be no droolsAlphaNetworkCompilationEnabled (false) either.

How to Reproduce?
Create a native Quarkus OptaPlanner with an EasyScoreCalculator
//Inject solverManager class:
import org.optaplanner.core.api.solver.SolverManager;
@Inject
SolverManager<OptimizationSolution, Integer> solverManager;
//Start a solver executable
solverManager.solveAndListen( id,
this::findById,
this::save,
this::saveFinal,
this::solverException
);
