Hi, we have this bug filed for BeanUtils, that seems to be related to generic collections used for indexed properties in conjunction with Java 7. In summary, when using a List<String> instead of a untyped List for an indexed property, PropertyUtils.getPropertyType will return null.
There is a proposed solution for this problem that basically flushes the cache of Introspector and reloads the property descriptors afterwards. It works, but it looks like a lot of additional reloading. I'm wondering if anybody has another idea how to work around this issue.
