    Description

      Very similar to the issue regarding the VariableListeners https://issues.redhat.com/browse/PLANNER-2308, the ChangeMoveSelectors are not being picked up by the optaplanner-quarkus extension, and when the native image is generated the exception below is produced.

      Solver configuration

      <constructionHeuristic>
    <changeMoveSelector>  
 <filterClass>org.kie.kogito.taskassigning.core.model.solver.filter.TaskByGroupAndSkillsChangeMoveFilter</filterClass>
    </changeMoveSelector>
  </constructionHeuristic>

      The workaround is the same as the reported in https://issues.redhat.com/browse/PLANNER-2308, by decorating the TaskByGroupAndSkillsChangeMoveFilter with the @RegisterForReflection annotation.

      By extending the reasoning, the issue above will happen in general with whatever class instantiated by OptaPlanner using reflection that is not being properly picked up by the extension.
