H T commented on JBSEAM-1306:
-----------------------------

Currently I have these to help fix this problem:

  @Transactional
  public long getLastFirstResult() {
    if (getResultCount() % getMaxResults() == 0) {
      return getResultCount() - getMaxResults();
    }
    return (long) Math.floor(getResultCount() / getMaxResults()) * getMaxResults();
  }

  @Override
  public boolean isNextExists() {
    return getResultList() != null &&
        (getFirstResult() == null ? 0 : getFirstResult() + getMaxResults()) < getResultCount();
  }
