> When creating a string during deserialization from data that we know is in
> the ASCII character set (each character can be represented by one byte) we
> currently read all the bytes into a temporary byte array and then create a
> String instance by giving it that byte array. The String constructor has to
> create its own char array and then copy all the bytes into it. After that the
> byte array is garbage.
> We could instead directly create a char array, fill it by reading each byte
> from the DataInput into it and then using reflection to directly set this
> char array as the value field of the String instance we just created (as an
> empty String). This prevents an extra copy of the data and reduces garbage
> creation.
