* fixed double ConversionFailedException nesting for ObjectToObjectConverter invocations
* BeanWrapper preserves annotation information for individual array/list/map elements
* Spring's constructor resolution consistently finds non-public multi-arg constructors
* revised constructor argument caching for highly concurrent creation scenarios
* revised constructor argument caching, avoiding a race condition for converted argument values
* SpEL passes full collection type context (generics, annotations) to ConversionService
* SpEL 'select last' operator now works consistently with maps
* BeanWrapper/DataBinder's "autoGrowNestedPaths" works for Maps as well
