Please run the following code:

import java.beans.*;

public class EnumTest {
    
    public class Bean {

        private int a;
        private int b;

        @BeanProperty(
                description = "A DESCRIPTION",
                enumerationValues = {
                    "javax.swing.SwingConstants.TOP"}
                )
        public void setA(int v) { a = v; }
        public int getA() { return a; }

        @BeanProperty(
                description = "B DESCRIPTION",
                enumerationValues = {
                    "javax.swing.SwingConstants.BOTTOM"}
                )
        public void setB(int v) { b = v; }
        public double getB() { return b; }
    }
    
    static void printEnum(PropertyDescriptor d) {
        Object en = d.getValue("enumerationValues");
        if (en == null) {
            System.out.println("null enumeration");
        } else {
            Object tmp[] = (Object []) en;
            for (Object o: tmp) {
                System.out.print(o + " ");
            }
            System.out.println("");
        }
    }


    public static void main(String[] args) throws Exception {

        BeanInfo i = Introspector.getBeanInfo(Bean.class, Object.class);
        PropertyDescriptor[] ds = i.getPropertyDescriptors();
        for (PropertyDescriptor d: ds) {
            System.out.println(d.getShortDescription());
            printEnum(d);
        }
    }
}


Expected (?) output:

A DESCRIPTION
TOP 1 javax.swing.SwingConstants.TOP
B DESCRIPTION
BOTTOM 3 javax.swing.SwingConstants.BOTTOM


Actual output:

A DESCRIPTION
TOP 1 javax.swing.SwingConstants.TOP
b
null enumeration



Could we use @BeanProperty more than once per bean? If no then how is it decided what property is top-priority?
