[FIXED] Spring web XML not respecting XmlRootElement in Java11

Issue

I migre my app to JDK11 (from JDK 8) so I up to springboot 2.2.4.RELEASE and I add com.fasterxml.jackson.dataformat:jackson-dataformat-xml

my model:

@XmlRootElement(name = "dataModel")
public class DataModel {
    ...
}

my controller:

@RequestMapping(value = "/{model}/columns", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<DataModel> getColumnsModel(@PathVariable String model) {
    LOGGER.info("getColumnsModel : model[{}]", model);
    DataModel dataModel = modelService.getColumns(model);
    return Optional.ofNullable(dataModel).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}

client:

curl -s --header "Accept: application/xml" http://localhost:8084/api/foo/columns

JDK8:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></dataModel>

JDK11:

<DataModel><columns><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></columns></DataModel>

new result is strang:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel> => <DataModel>

<dataModel><columns>author</columns>...</dataModel> => <DataModel><columns><columns>author</columns>...</columns></DataModel>

I try add this dependencies but do not resolve:

    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.1</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>2.3.0.1</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.2</version>
    </dependency>

Solution

remove this:

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>
