It appears that the amount to grow the array is not taking into account
that before the System.arraycopy we first store 'type' and increment the
offset :-

150                 firstSegmentsBuffer[firstSegidx++] = type;


Fix is to add 1 to the amount to grow the array.  "type - 2 + 1" looks
a bit inefficient but is a closer match to what is being added and I'd
like to think javac simplifies the expression.
