### Bug Type (问题类型) others (please edit later) ### Before submit - [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - SonarQube block issue [java:S2095] Connections, streams, files, and other classes that implement the Closeable interface or its super-interface, AutoCloseable, needs to be closed after use. Further, that close call must be made in a finally block otherwise an exception could keep the call from being made. Preferably, when class implements AutoCloseable, resource should be created using "try-with-resources" pattern and will be closed automatically. Failure to properly close resources will result in a resource leak which could bring first the application and then perhaps the box the application is on to their knees. ### Expected & Actual behavior (期望与实际表现) ```java // Multiple steps, construct first step to iterator Iterator<Edge> edges = this.edgesOfVertexWithCount(source, firstStep); // Wrap steps to Iterator except last step for (int i = 1; i < stepNum - 1; i++) { EdgeStep currentStep = steps.get(i); edges = new FlatMapperIterator<>(edges, (edge) -> { Id target = ((HugeEdge) edge).id().otherVertexId(); return this.edgesOfVertexWithCount(target, currentStep); }); } ``` close FlatMapperIterator after usage ### Vertex/Edge example (问题点 / 边数据举例) _No response_ ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构) _No response_ -- This is an automated message from the Apache Git Service.
