Deserialization: empty String field to null value doesn't work

[danibs]

Hi.
I'm using <jackson-bom.version>2.17.2</jackson-bom.version> and already resolved my problem with Date using this configuration #561 (comment) .

Now what I want is to convert:

<x><TESTO></TESTO></x>

to the field:

	@JsonProperty( "TESTO" )
	private String testo;

and when the text is empty what I want is to have null in testo field.
What I already tried is all the combinations of:

XmlMapper mapper = new XmlMapper();

mapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);
mapper.coercionConfigFor( LogicalType.Textual ).setCoercion( CoercionInputShape.EmptyString, CoercionAction.AsNull );

I also tried adding:

mapper.coercionConfigDefaults().setCoercion(  CoercionInputShape.EmptyString, CoercionAction.AsNull);

Then I tried to debug but it seams that coercion is not used.

Any idea?

Thanks alot
