The only thing I'd question is how much does this increase the memory foot print of an application. It looks like for every entity you have mapped in your application you will have a cache (map) of column name to index number. This is probably ok, unless your application has thousands or entities. Either way, nice find. Pretty interesting find, I’ve worked with hibernate for quite a while now and never knew about this feature.
