在调用TopologyValidator.validate()方法时，部分数据会导致后台崩溃，请问是什么原因？
boolean flag = TopologyValidator.preprocess(new DatasetVector[]{(DatasetVector) dataset},ints,topoTolerance, (SteppedListener) null);
if(flag){
DatasetVector topologyResult = TopologyValidator.validate(datasetVector, null, processTopologyRule(checkType), topoTolerance, null, datasource, datasource.getDatasets().getAvailableDatasetName(tableName+"_result"), (SteppedListener) null); }
