> Jackson 2.12.x changed the default for the 'EMPTY_ELEMENT_AS_NULL' feature from true to false (see [here|[https://github.com/FasterXML/jackson-dataformat-xml/issues/411]]) and we can enable back this property using XMLMapper:
> {quote}xmlMapper.configure(FromXmlParser.Feature.EMPTY_ELEMENT_AS_NULL, true);
> {quote}
> However, there's no way to enable this behaviour in jaxonxml inside camel routes. In the [documentation|[https://camel.apache.org/components/3.14.x/dataformats/jacksonxml-dataformat.html#_enabling_or_disable_features_using_jackson],] It's specified that we can enable or disable certain types of properties that are inside SerializationFeature, DeserializationFeature and MapperFeature but there's no way to enable EMPTY_ELEMENT_AS_NULL since is in another enum (FromXmlParser). We've tried enabling the feature ACCEPT_EMPTY_STRING_AS_NULL_OBJECT but that doesn't work either.
> We've managed to implement a workaround by using <bean> instead of <jacksonxml> in our camel routes (we use Camel XML DSL), but that's not efficient as we would have to replace all <jacksonxml> references. So we need to have the possibility to enable back EMPTY_ELEMENT_AS_NULL from <jacksonxml> in camel XML DSL.
