Hi Sebastian,

I did suggest adding @Deprecated to the Boolean constructors, but only in your 
own source tree, as a quick means of causing the compiler to emit warnings for 
places where they're used. I don't think we should actually go ahead and 
deprecate them at this time. So, please drop the deprecation changes from your 
patch. Sorry for the misunderstanding.

(As I've mentioned elsewhere, there is forthcoming work in the area of 
deprecation, so the Boolean constructors will eventually be marked in some way 
so that developers will be advised to update their code.)

I do think the cleanup work to remove usages of the Boolean constructors is 
worthwhile and that you should proceed with it.
