MapStruct throws an exception during collection update mapping when target is immutable and there is no target read accessor

[filiphr]

The error happens when we have something like:

public class Source {

    public Set<String> getProperty() {
    }
}

public class Target {

    public void setProperty(Set<String> property) {
    }
}

A workaround is to set the Mapper#collectionMappingStrategy to CollectionMappingStrategy.TARGET_IMMUTABLE
