public boolean isSpecialException(RVVException e, RegionVersionHolder holder) {
    // deltaGII introduced a special exception, i.e. the hone is not in the middle, but at the end
    // For example, P was at P3, operation P4 is on-going and identified as unfinished operation.
    // The next operation from P should be P5, but P's currentVersion() should be 3. In holder,
    // it's described as P3(2-4), i.e. exception.nextVersion == holder.version + 1
    return (e != null && e.nextVersion == holder.version + 1);
  }
Returns true if this version hold has an exception in the exception list for the given version
number.

This differs from contains because it returns true if v is greater than the last seen version
for this holder.
