    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
