A DESCRIPTION OF THE PROBLEM :
I get different results when the java code below is executed.

Java(TM) SE Runtime Environment (build 1.8.0_31-b13) returns:
class: java.beans.PropertyDescriptor
paymentComponentList: java.beans.IndexedPropertyDescriptor

Java(TM) SE Runtime Environment (build 1.8.0_74-b02) returns:
 class: java.beans.PropertyDescriptor
paymentComponentList: java.beans.PropertyDescriptor

Here is the java code:
import java.beans.BeanInfo;
import java.beans.IntrospectionException;
import java.beans.Introspector;
import java.beans.PropertyDescriptor;
import java.util.ArrayList;

public class DescriptorTest {
        private ArrayList<Integer> paymentComponentList = new ArrayList<Integer>();

        public Integer getPaymentComponentList(int index) {
                final int size = paymentComponentList.size();
                if (size > index) {
                        return paymentComponentList.get(index);
                } else {
                        return null;
                }
        }

        public void setPaymentComponentList(ArrayList<Integer> paymentComponentList) {
                this.paymentComponentList = paymentComponentList;
        }

        public static void main(String[] args) {
                BeanInfo beanInfo = null;
                PropertyDescriptor descriptors[] = null;
                try {
                        beanInfo = Introspector.getBeanInfo(DescriptorTest.class);
                } catch (IntrospectionException e) {
                        System.err.println(e.toString());
                }
                descriptors = beanInfo.getPropertyDescriptors();
                for (PropertyDescriptor d : descriptors) {
                        System.out.println(d.getDisplayName() + ": "
                                        + d.getClass().getCanonicalName());
                }
        }

}
