Hi Ted,

I don't think there's jar hell.

If users want to use 1.2, they do. If they want to upgrade to new  
features in 2.0, they have to also accommodate the incompatible  
changes in other methods.

It's not clear to me how renaming the packages improves anything.

If you want to have a method that does something different, you can  
always create a new method with a different signature and tell users  
to use that method instead of the old one.

I am probably missing your definition of jar hell... ;-)
