Companies indeed hired someone (Asian) almost as good elsewhere for a fraction of cost.

That was a niche optimization primarily targeting code at intepretor. Even the most basic optimizing compiler in HotSpot tiered compilation chain at that time (the client compiler or C1) would be able to optimize that into the register. Since String is such an important class, even small stuffs like this is done.

So basically you doesn't have any non trivial example. What else but to be expected?
