Peculiar fruits in the JDK

[Ulf Zibis]

Also I've found out, that MASK1 is superfluous, because on implicit 
converting from char to int all upper bits are automaticlly 0. So we can 
code instead:

           char c = c2bMap.charAt(c2bMapIndex[current >> SHIFT] + 
(current & MASK));

           char c = (current < '\u0100') ? c2bMap.charAt(current) :
               c2bMap.charAt(c2bMapIndex[current >> SHIFT] + (current & 
MASK));
