Namespace null does not match expected ""

Hi,

not sure what I’m missing but after updating to kotlinx-serialization-runtime 0.20.0 and xmlutil-serialization-jvm 0.20.0.0 (from 0.14.0 and 0.14.0.2).

Following code:

@Serializable
@XmlSerialName(value = "metadata", namespace = "", prefix = "")
data class Metadata(
    @XmlElement(true)
    val groupId: String = "NONE",
    @XmlElement(true)
    val artifactId: String = "NONE",
    @XmlElement(true)
    val version: String = "NONE"
)

fun main() {

    val response = """<?xml version="1.0" encoding="UTF-8"?>
<metadata>
    <groupId>com.test</groupId>
    <artifactId>test</artifactId>
    <version>1.0.0-SNAPSHOT</version>
</metadata>"""

    val xmlMapperX = XML {
        indent = 4
    }

    println(xmlMapperX.parse(Metadata.serializer(), response))
}

Produces:

Exception in thread "main" nl.adaptivity.xmlutil.XmlException: Namespace null does not match expected ""

The workaround is using woodstox as stax runtime: runtimeOnly("com.fasterxml.woodstox:woodstox-core:5.0.3"). I’ve also pushed a fix to master that should work. Please have a look. I’ll try to push it tomorrow - I’ve been crazy buzy these last days moving all teaching online with 3 days preparation time (including getting to the office to pick up things before we’re not supposed to be in the office anymore).

Should now work again in 0.20.0.1
