org.apache.derby.iapi.services.io.FormatableBitSet.grow()
Grow (widen) a FormatableBitSet so that it contains at least N bits. If the bitset already has more than n bits, this is a noop. Negative values of n are not allowed. ASSUMPTIONS: that all extra bits in the last byte are zero. @param n The number of bits you want. The bits arealways added as 0 and are appended to the least significant end of the bit array.

      // add a new bit to the bit set. If DROP, then remove the bit
      // for the dropped column.
      if (columnDescriptor == null)
      {
        int currentLength = columns.getLength();
        columns.grow(currentLength+1);
      }
      else
      {
