I still more like the break-to-label approach. It looks more logical and saves one comparison. This 
might count on very very short strings, but I would rename it to something like find1stUpperCase: or 

As an alternative you could write "if (first >= len)" as counterpart to the last "first < len" 
operation in the for loop, which therefore should be merged by JIT.
(Or use "first != len" in the for loop.)
