javascript - 大负载上的 WSO2ESB js 脚本调解器错误

Question

我有一个 seq (WSO2ESb 4.9) 调用 REST 并接收 JSON。然后我通过脚本中介 (JS) 将 JSON 映射到 XML，这是我的配置:

<case regex="urn:mta:navigation:getMarshes">
                <property xmlns:ns="http://ws.apache.org/ns/synapse" name="uri.var.service"
                    value="getMarshes" scope="default" type="STRING" />
                <call>
                    <endpoint key="adapter.navigation.asu.GetData.Endpoint" />
                </call>
                <script language="js"><![CDATA[
                            var array = mc.getPayloadJSON();
                            var payload = <getMarshesRS/>;     

                            for (i = 0; i < array.length; ++i) {
                                var elem = array[i];
                                payload.Marshes += <marsh id={elem.mr_id} num={elem.mr_num} title={elem.mr_title} note={elem.mr_note} mt_id={elem.mrt_id} />
                            }
                            mc.setPayloadXML(payload);
                ]]></script>
</case>

如果我从 REST 服务接收到的对象不多(例如 10 个)，它工作正常。但是如果我收到了1280个对象，我就异常了

这是一个错误吗？

ESB 中有一个错误，您无法使用脚本中介程序处理大量有效负载，这是来自 underline Rhino 引擎。以下是为此的 JIRA。但是您的堆栈跟踪有些不同。
