Description

PropertyUtils.getPropertyType() for IndexedProperty works only for first invoked descendant class.

Bug reproduced in JDK 1.7.0.10 - 13. In JDK 1.7.0.9 it works fine. As I see, in JDK 1.7.0.10 java.beans.Introspector was changed, but I don't understand how it works.

Example

file is IndexedProperty of the RootBean (attachend to issue) with type ArrayList<String>.

RoootBean has two empty descendans: FirstChildBean and SecondChildBean.

RootBean bean = new FirstChildBean();
Class propertyType = PropertyUtils.getPropertyType(bean, "file[0]");
System.out.println(propertyType != null ? propertyType.getName() : null);
-- Expected: java.lang.String, Actual: java.lang.String

bean = new SecondChildBean();
propertyType = PropertyUtils.getPropertyType(bean, "file[0]");
System.out.println(propertyType != null ? propertyType.getName() : null);
-- Expected: java.lang.String, Actual: null
