Buggy source:
public boolean handleValidate(Object obj){
  CrosstabReportItemHandle crosstab=getCrosstabCellHandle().getCrosstab();
  if (obj instanceof Object[]) {

    int len=objects.length;

      return false;
    }

        if (temp instanceof MeasureHandle || temp instanceof MeasureGroupHandle) {
          if (crosstab.getCube() == CrosstabAdaptUtil.getCubeHandle((DesignElementHandle)temp)) {
            continue;

Fixed version (ground truth):
public boolean handleValidate(Object obj){
  CrosstabReportItemHandle crosstab=getCrosstabCellHandle().getCrosstab();
  if (obj instanceof Object[]) {
    Object[] objects=(Object[])obj;
    int len=objects.length;
    if (len == 0) {
      return false;
    }
    if (len == 1) {
      return handleValidate(objects[0]);
    }
 else {
      for (int i=0; i < len; i++) {
        Object temp=objects[i];
        if (temp instanceof MeasureHandle || temp instanceof MeasureGroupHandle) {
          if (getPositionType().equals(ICrosstabCellAdapterFactory.CELL_MEASURE) && crosstab.getCube() == CrosstabAdaptUtil.getCubeHandle((DesignElementHandle)temp)) {
            continue;
          }
 else {
            return false;
          }
        }
 else {
          return false;
        }
      }
      return true;
    }
  }
  if (obj instanceof DimensionHandle) {
    if ((getPositionType().equals(ICrosstabCellAdapterFactory.CELL_LEVEL_HANDLE) || getPositionType().equals(ICrosstabCellAdapterFactory.CELL_FIRST_LEVEL_HANDLE)) && CrosstabUtil.canContain(crosstab,(DimensionHandle)obj)) {
      return true;
    }
