Cannot serialize/deserialize custom types into a collection

[Valentine]

I use the following configuration:

public class TestSettings extends YamlSerializable {

    @Transient
    private static final SerializerConfig CONFIG = new SerializerConfig.Builder()
            .setCommentValueIndent(1)
            .registerSerializer(new TestSerializer())
            .build();
    @Transient
    public static final TestSettings IMP = new TestSettings();

    public TestSettings() {
        super(CONFIG);
    }

    public TEST_SECTION TEST_SECTION = new TEST_SECTION();

    public static class TEST_SECTION {

        public TestData DATA = new TestData(Collections.singletonList("test"));

    }

}

Custom type for serialization:

@NoArgsConstructor
@AllArgsConstructor
@Data
public class TestData {

    private List<String> originalList = new ArrayList<>();

}

Custom serialization class. From TestData to List with String type.

public class TestSerializer extends ClassSerializer<TestData, List<String>> {

    @Override
    public List<String> serialize(TestData from) {
        return from.getOriginalList();
    }

    @Override
    public TestData deserialize(List<String> from) {
        return new TestData(from);
    }

}

Exception when attempting to load a configuration:

Is this a serializer bug or is this behavior simply not supported at this time?
