XJC generates deprecated `Integer(java.lang.String)`

[KrohnicDev]

The tool generates code which has been deprecated:

    public Integer unmarshal(String value) {
        return new Integer(value);
    }

'Integer(java.lang.String)' is deprecated since version 9 and marked for removal

I am not sure whether this could be avoided by configuration. Currently I am using plugin version 1.8.2 and org.glassfish.jaxb:jaxb-xjc:4.0.5.

Configuration is as follows:

xjc {
    xsdDir = file("my-xsd-dir/xsd")
    includes = listOf("my-schema.xsd")
    bindingFiles.setFrom("my-bindings.xml")
}

I tried setting xjcVersion to 4.0.5 but there was no difference.
