> 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.
