Description

I run into a problem when using Struts to populate request parameters to a
form's nested property when either the conversion from String to int (for
example) fails or when the set method in the nested bean throws an exception
such as IllegalArgumentException.

I propose that we add a property to BeanUtilsBean for a new interface called
something like PopulateExceptionHandler which will have a method something like
void execute(Exception exception, Object bean, String propertyPath, Object
value)

Then, within BeanUtilsBean.populate, within the loop, it would catch any
exception, and call the populateExceptionHandler's execute method with it
(unwrapping InvocationTargetException's). The default handler would just
rethrow it (or we could have no default handler, and if no handler is present,
the BeanUtils method rethrows it).
