FULL PRODUCT VERSION :
I tested on java 8 any release

ADDITIONAL OS VERSION INFORMATION :
Windows 7

A DESCRIPTION OF THE PROBLEM :
The changes made in the Introspector processPropertyDescriptors method are resposible for the following issue:

An index type property is not detected correctly in a subclass if it is using overloaded methods of the same property defined in a super class.


REGRESSION.  Last worked in version 7u80

ADDITIONAL REGRESSION INFORMATION: 
any java 8 version, did tests on the 66 and 45 updates

java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I have the following class structure

public class SuperClass {

    private String tagTemplate;

    public String getTagTemplate() {
        return tagTemplate;
    }

    public void setTagTemplate(String tagTemplate) {
        this.tagTemplate = tagTemplate;
    }
}


public class SubClass extends SuperClass {

    private Hashtable<Integer, Point> tagTemplateType = new Hashtable<Integer, Point>();

    public Point getTagTemplate(int index) {
        return tagTemplateType.get(index);
    }

    public void setTagTemplate(int index, Point tagType) {
        tagTemplateType.put(index, tagType);
    }
}


I run the following code

/**
 * @author Radu Barbos
 */
public class TestBeans {

    public static void main(String arg[]) {
        new TestBeans().test(SubClass.class);
    }

    private void test(Class<?> beanClass) {
        PropertyDescriptor descriptors[] = null;
        // Introspect the bean and cache the generated descriptors
        BeanInfo beanInfo = null;
        try {
            beanInfo = Introspector.getBeanInfo(beanClass);
        } catch (IntrospectionException e) {
            return;
        }
        descriptors = beanInfo.getPropertyDescriptors();
        for(PropertyDescriptor pd: descriptors) {
            System.out.println("--> " + pd.getName() + " " + (pd instanceof IndexedPropertyDescriptor));
        }
    }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The expected output will be if the 'tagTemplate' property will be reprsented by a 'IndexedPropertyDescriptor' and the read/write methods should be the SubClass methods.

This behaviour is what happends in java 7
ACTUAL -
The 'tagTemplate' property is described by a 'PropertyDescriptor' and is represents the SuperClass methods, this is wrong and I'm extracting the SubClass properties.



REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
- do not use overloaded methods to represent index type properties in subclasses
