please use AnonymousClassBeanPropertyTest from http://cr.openjdk.java.net/~avstepan/8154962/webrev.00/index.html to reproduce

tests affected: testGetArray, testSetArray, testGetBoth_2, testSetBoth_2, testGetSetBoth_1, testGetSetBoth_2 - the output for them will be "null enumerationValues"

is that what expected? Please note that, e.g., cases testGetBoth_1 and testSetBoth_1 do not fail.

JDK9 b114 + Win. 7


Please note also that at the same time the indexed getter could be annotated in such a way that the enumerationValues will be non-null (using SimpleBeanInfo extension instead of the annotation):

import java.beans.*;

public class IndexedPropTest {

    private final static double X = java.lang.Math.PI;
    private final static String X_NAME = "java.lang.Math.PI", X_SHORT = "PI";

    public static class C {
        public double[] getX() { return new double[]{X, X}; }
    }

    public static class CBeanInfo extends SimpleBeanInfo {

        @Override
        public PropertyDescriptor[] getPropertyDescriptors() {
            PropertyDescriptor[] p = new PropertyDescriptor[1];

            try {
                p[0] = new PropertyDescriptor ("x", C.class, "getX", null);
                p[0].setValue("enumerationValues", new Object[]{X_SHORT, X, X_NAME});
            } catch(IntrospectionException e) { throw new RuntimeException(e); }
            return p;
        }
    }

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

        BeanInfo i = Introspector.getBeanInfo(C.class, Object.class);
        PropertyDescriptor d[] = i.getPropertyDescriptors();
        if (d.length < 1) { System.out.println("no descriptors"); }
        else {
            Object vals[] = (Object[]) d[0].getValue("enumerationValues");
            for (Object v: vals) { System.out.println(v); }
        }
    }
}

////// Output:
PI
3.141592653589793
java.lang.Math.PI
