Steps to reproduce issue:

**Root**

    package example;

    import javax.xml.bind.annotation.XmlRootElement;
    import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
    
    @XmlRootElement
    public class Root {
    
        @XmlJavaTypeAdapter(AAdapter.class)
        public A<B> a;
    
    }

**A**

    package example;

    public class A<T> {
    
        public T t;
    
    }

**AAdapter**

    package example;

    import javax.xml.bind.annotation.adapters.XmlAdapter;
    
    public class AAdapter<T> extends XmlAdapter<T, A<T>> {
    
        @Override
        public A<T> unmarshal(T v) throws Exception {
            return new A<T>();
        }
    
        @Override
        public T marshal(A<T> v) throws Exception {
            return v.t;
        }
    
    }

**B**

    package example;

    public class B {
    
    }

**Demo**

    package example;

    import javax.xml.bind.JAXBContext;
    import javax.xml.bind.Marshaller;
    
    public class Demo {
    
        public static void main(String[] args) throws Exception {
            JAXBContext jc = JAXBContext.newInstance(Root.class, B.class);
    
            Root root = new Root();
            A<B> a = new A<B>();
            a.t = new B();
            root.a = a;
    
            Marshaller marshaller = jc.createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            marshaller.marshal(root, System.out);
        }
    
    }

**Output**

    <?xml version="1.0" encoding="UTF-8"?>
    <root>
       <a>example.B@3ecfff</a>
    </root>

**Expected Output**

    <?xml version="1.0" encoding="UTF-8"?>
    <root>
        <a xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="b"/>
    </root>
