I am getting IllegalArgumentException key already registered on a custom lombok handler.

@ProviderFor(EclipseAnnotationHandler.class)
public class HandleEntityData extends EclipseAnnotationHandler<EntityData> {

@Override
    public void handle(AnnotationValues<EntityData> annotation,
            Annotation ast,
            EclipseNode annotationNode) {

        handleFlagUsage(
             annotationNode, 
             new ConfigurationKey<FlagUsageType>("lombok.entity.flagUsage", 
                    "Emit a warning or error if @EntityData is used.") {}, 
                        "@EntityData"
        ); 


}

I already checked that the key is unique. And so wondering if anyone had ideas why ?

Found the answer to my own question. Basically moved the CONFIGURATION keys as a separate static constant so that it does not get constructed everytime handle() is called. (The identity of the key object seems to fallback to Object equals/hashcode.)

@ProviderFor(EclipseAnnotationHandler.class)
public class HandleEntityData extends EclipseAnnotationHandler<EntityData> {

 public final static ConfigurationKey CONFIGURATION_KEY = new ConfigurationKey<FlagUsageType>("lombok.entity.flagUsage", 
                    "Emit a warning or error if @EntityData is used.") {};

@Override
    public void handle(AnnotationValues<EntityData> annotation,
            Annotation ast,
            EclipseNode annotationNode) {

        handleFlagUsage(
             annotationNode, 
             CONFIGURATION_KEYS, 
                        "@EntityData"
        ); 


}
