The method orElse(PersistentProperty<?>) in the type Optional<PersistentProperty<?>> is not applicable for the arguments(Object)

Question

Any help or hint would be greatly appreciated it!!! I am using open jdk 11. Based o this line 65:

I am getting this error: The method orElse(PersistentProperty) in the type Optional> is not applicable for the arguments(Object)

This is the code:

private void processResourceId(MongoPersistentEntity<?> entity, PersistentPropertyAccessor<Object> sourceAccessor, UUID uuid) {
    //  PersistentProperty<?> resProperty = (PersistentProperty)this.getGeneratedResourceIdProperty(entity.getType(), entity).orElse((Object)null);
    PersistentProperty<?> resProperty = (PersistentProperty)this.getGeneratedResourceIdProperty(entity.getType(), entity).orElse((Object)null);

    if (resProperty != null && resProperty.getType() == String.class) {
        if (this.isStringPropertyHasText(sourceAccessor, resProperty)) {
            Object id = this.getUuidString(uuid);
            sourceAccessor.setProperty(resProperty, id);
        }
    }
}
