As David indicated, there is no "problem" with a bridge method being 
marked final (or strictfp) in the class file. It's syntactically legal 
(access_flags allows it) and semantically level (you can meaningfully 
have a bridge method that is not overrideable).

My concern is with unforeseen consequences at the language level. Today 
it is possible to override a bridge method - yes, it's almost certainly 
accidental, but if we start making some bridge methods final then some 
programs are going to break. But, the number of such programs will be 
low, and arguably they never deserved to compile. So, I would go ahead 
with the bug fix.
